OCCUPATIONAL HEALTH AND SAFETY POLICIES AND PROCEDURES
Occupational Health and Safety (OHS) Policy – An Information and
communication technology (ICT) student should know how to behave when working
in the computer laboratory, as well as implement a safe way of accomplishing every
task. Safety practices should be learned early and always adheres in working with
any electrical and electronic device, including personal computers and its
peripherals. This is for your protection as well as to the people working with you,
33
and for the devices that you are using. The basis for this process begins with
Occupational Health and Safety Policies.
Occupational safety and health (OSH) is a planned system of working to prevent
illness and injury where you work by recognizing and identifying hazards and risks.
Health and safety procedure is the responsibility of all persons in the computer and
technology industries. You must identify the hazards where you are working and
decide how dangerous they are. Eliminate the hazard or modify the risk that it
presents.
Occupational Health and Safety standards
Each student has a responsibility to their colleagues and their organization to
report and act upon any potential workplace hazard. Students need to be aware of
the type of hazards that are possibly present in their work environment.
Procedure
1. Identify the hazard
2. Clear the area close to the hazard
3. Partition the hazard off or clearly identify the area to protect other people
from harm
4. If the hazard is easily and safely cleared, then do so
If not…
5. Report the hazard to the appropriate person (such as teacher in charge,
principal etc.) to obtain assistance
6. Following clearing of the hazard fill out the correct documentation to assist
in identifying improved practice to reduce further incidence of hazards.
All hazards must be reported using Accidental Report form. This enables us to
track the kinds of hazards we have in our workplace, and take action where
necessary to make it safer for all student and clients.
Accident reports
Forms are used to give specific details with regards to the accidents
happened in the laboratory during experiments.
Accident reports contain the following details:





Name of the person injured
Date and time of the accident

professional assistance is required:
A. Call the supervisor or manager and advise them of the problem and the
urgency of the matter.
B. Depending on the risk it may be called as an evacuation.
C. Follow the evacuation procedure.
D. The supervisor or manager will call in the fire brigade or specialized
personnel who will deal with the spill.
Fire exits
All fire exits should be kept clear of from obstacles. All students have a
responsibility to make sure that chairs, empty boxes or any other type of obstacle are
not placed in or near fire exit doorways.
All corridors also need to have equipment stored on one side only to ensure
that in the event of an emergency there is a clear exit.
Fire Safety Procedure
Each work area has a designated fire warden, who in the event of a fire will take
charge. They are recognized by the wearing of a red hard hat.

UNDERSTANDING COMPUTER
A computer is one of the most brilliant inventions of mankind. Thanks to the
computer technology, we were able to achieve storage and processing of huge
amounts of data; we could rest our brains by employing computer memory capacities
for storing information. Due to computers, we have been able to speed up daily work,
carry out critical transactions and achieve accuracy and precision in work.
Computers of the earlier years were of the size of a large room and were required to
consume huge amounts of electric power. However, with the advancing technology,
computers have shrunk to the size of a small watch. Depending on the processing
power and size of computers, they have been classified under various types. Let us
look at the classification of computers.
Different Types of Computers
Based on the operational principle of computers, they are categorized as
analog, digital and hybrid computers.
Analog Computers: These are almost extinct today. These are different from a
digital computer because an analog computer can perform several mathematical
operations simultaneously. It uses continuous variables for mathematical operations
and utilizes mechanical or electrical energy.
37
Figure1. Different Types of Computer
Digital Computers: They use digital circuits and are designed to operate on two
states, namely bits 0 and 1. They are analogous to states ON and OFF. Data on
these computers is represented as a series of 0s and 1s. Digital computers are
suitable for complex computation and have higher processing speeds. They are
programmable. Digital computers are either general purpose computers or special
purpose ones. Special purpose computers, as their name suggests, are designed for
specific types of data processing while general purpose computers are meant for
general use.
Hybrid Computers: These computers are a combination of both digital and analog
computers. In this type of computers, the digital segments perform process control
by conversion of analog signals to digital ones.
Classification of Computers
The following are the classification of the different types of computers based
on their sizes and functionalities:
Mainframe Computers: Large organizations use mainframes for highly critical
applications such as bulk data processing and ERP. Most of the mainframe
computers have the capacities to host multiple operating systems and operate as a
number of virtual machines and can substitute for several small servers.
Minicomputers: In terms of size and processing capacity, minicomputers lie in
between mainframes and microcomputers. Minicomputers are also called mid-range
38
systems or workstations. The term began to be popularly used in the 1960s to refer
to relatively smaller third generation computers.
Servers: They are computers designed to provide services to client machines in a
computer network. They have larger storage capacities and powerful processors.
Running on them are programs that serve client requests and allocate resources like
memory and time to client machines. Usually they are very large in size, as they
have large processors and many hard drives. They are designed to be fail-safe and
resistant to crash.
Supercomputers: The highly calculation-intensive tasks can be effectively
performed by means of supercomputers. Quantum physics, mechanics, weather
forecasting, molecular theory are best studied by means of supercomputers. Their
ability of parallel processing and their well-designed memory hierarchy give the
supercomputers, large transaction processing powers.
Figure2. Classification of Computer
39
Microcomputers: A computer with a microprocessor and its central processing unit
it is known as a microcomputer. They do not occupy space as much as mainframes
do. When supplemented with a keyboard and a mouse, microcomputers can be
called personal computers. A monitor, a keyboard and other similar input output
devices, computer memory in the form of RAM and a power supply unit come
packaged in a microcomputer. These computers can fit on desks or tables and prove
to be the best choice for single-user tasks.
Personal computers come in different forms such as desktops, laptops and
personal digital assistants (refer to Figure 3). Let us look at each of these types of
computers.
Desktops: A desktop is intended to be used on a single location. The spare parts of
a desktop computer are readily available at relatively lower costs. Power
consumption is not as critical as that in laptops. Desktops are widely popular for daily
use in the workplace and households.
Laptops: Similar in operation to desktops, laptop computers are miniaturized and
optimized for mobile use. Laptops run on a single battery or an external adapter that
charges the computer batteries.
Figure3. Types of Personal Computer
40
Netbooks: They fall in the category of laptops, but are inexpensive and relatively
smaller in size. They had a smaller feature set and lesser capacities in comparison
to regular laptops, at the time they came into the market.
Personal Digital Assistants (PDAs): It is a handheld computer and popularly
known as a palmtop. It has a touch screen and a memory card for storage of data.
PDAs can also be used as portable audio players, web browsers and smart phones.
Most of them can access the Internet by means of Bluetooth or Wi-Fi
communication.
Tablet Computers: Tablets are mobile computers that are very handy to use. They
use the touch screen technology. Tablets come with an onscreen keyboard or use a
stylus or a digital pen. Apple's iPod redefined the class of tablet computers.
Wearable Computers: A record-setting step in the evolution of computers was the
creation of wearable computers. These computers can be worn on the body and are
often used in the study of behavior modeling and human health. Military and health
professionals have incorporated wearable computers into their daily routine, as a
part of such studies. When the users' hands and sensory organs are engaged in
other activities, wearable computers are of great help in tracking human actions.
Wearable computers do not have to be turned on and off and remain in operation
without user intervention.
Direction: Identify the type of computer being described in the following sentences
and write your answer on a separate sheet of paper.
1. These are mobile computers that are very handy to use.
2. They are computers designed to provide services to client machines in a
computer network.

COMPUTER SYSTEM, DEVICES AND PERIPHERALS
As an aspiring computer technician, it is very important to know the system
that runs your computer and different devices attached to it. Each device plays an
important role, without each other computer system will not work properly.
What is an Operating System?
The operating system is the most
important program that runs on a computer. Every
general-purpose computer must have an operating
system to run other programs. Operating systems
perform basic tasks, such as recognizing input from
the keyboard, sending output to the display screen,
keeping track of files and directories on the disk,
and controlling peripheral devices such as disk
drives and printers.
For large systems, the operating system has
even greater responsibilities and powers. It is like a
traffic cop -- it makes sure that different program and users running at the same time
do not interfere with each other. The operating system is also responsible
for security, ensuring that unauthorized users do not access the system.
Operating systems can be classified as follows:
o Multi-user: Allows two or more users to run programs at the same time.
Some operating systems permit hundreds or even thousands of
concurrent users.
Linux
Unix
Windows 2000
o Multiprocessing : Supports running a program on more than one CPU.
Linux
Unix
Windows 2000
o Multitasking : Allows more than one program to run concurrently.
Unix
Windows 2000 and Windows multi point
o Multithreading : Allows different parts of a single program to run
concurrently.
42
Linux
Unix
Windows 2000 and Windows 7
o Real time: Responds to input instantly. General-purpose operating
systems, such as DOS and UNIX, are not real-time.
Operating
systems
provide
a software platform on
which
other application programs can run. The application programs must be written to run
on top of a particular operating system. Your choice of operating system, therefore,
determines to a great extent the applications you can run. For PCs, the most popular
operating systems are DOS, OS/2, and Windows, but others are available, such
as Linux.
What are the devices of a computer?
The physical, touchable, electronic and mechanical parts of a computer are
called the hardware which is composed of different devices attached to the
computer.
The following list represents a basic set of devices found in most Personal
Computers.
1. System Unit- The main part of a microcomputer, sometimes called the chassis. It
includes the following parts: Motherboard, Microprocessor, Memory Chips, Buses,
Ports, Expansion Slots and Cards.
Figure4. Tower Type System Unit
43
2. Motherboard / Mainboard / System Board- The main circuit board of a
computer. It contains all the circuits and components that run the computer.
Figure5. Modern Motherboard
3. CPU (Central Processing Unit) - The processor is the main ―brain‖ or ―heart‖ of a
computer system. It performs all of the instructions and calculations that are needed
and manages the flow of information through a computer.
Figure6. Examples of CPU (Intel Core 2 Duo and AMD Athlon)
4. Primary storage- (internal storage, main memory or memory) is the computer's
working storage space that holds data, instructions for processing and processed
data (information) waiting to be sent to secondary storage. Physically, primary
storage is a collection of RAM chips.
44
Two (2) Types of Memory
a. ROM – (Read Only Memory) ROM is non-volatile, meaning it holds data even
when the power is ON or OFF.
b. RAM – (Random Access Memory) RAM is volatile, meaning it holds data only
when the power is on. When the power is off, RAM's contents are lost.
Figure 7.Examples of RAM
5. Expansion Bus - A bus is a data pathway between
several hardware components inside or outside a
computer. It does not only connect the parts of the CPU to
each other, but also links the CPU with other important
hardware.
Figure 8.Expansion Bus
6. Adapters- Printed-circuit boards (also called interface
cards) that enable the computer to use a peripheral
device for which it does not have the necessary
connections or circuit boards. They are often used to
permit upgrading to a new different hardware.
Figure 9. Adapter (Network Adapter)
45
7. Power Supply Unit (PSU) - Installed in the back corner
of the PC case, next to the motherboard. It converts
120vac (standard house power) into DC voltages that are
used by other components in the PC.
Figure10. Power supply
8. Hard Disk Drive (HDD) - Also known as hard drive,
is a magnetic storage device that is installed inside the
computer. The hard drive is used as permanent
storage for data. In a Windows computer, the hard
drive is usually configured as the C: drive and contains
the operating system and applications.
Figure 11.Hard Disc
9. Optical Drive- An optical drive is a storage
device that uses lasers to read data on the optical
media. There are three types of optical drives:
Compact Disc (CD), Digital Versatile Disc (DVD)
and Blu-ray Disc (BD).
Figure12. CD ROM
10. Digital Versatile Disc (DVD) - Designed to
optically access data stored on a DVD. A laser
moves back and forth near the disk surface and
accesses data at a very fast rate.
Figure 13.DVD ROM
What are the input and output devices of a computer?
The devices attached to a personal computer can be classified into two- the
input and output devices. Input Device is composed of a device that accepts data
and instructions from the user or from another computer system. While, output
46
device is any piece of computer hardware that displays results after the computer
has processed the input data that has been entered.
Two (2) Types of Input Devices
1. Keyboard Entry – Data is inputted to the computer through a keyboard.
Keyboard - The first input device developed for the PC. Data is transferred to
the PC over a short cable with a circular 6-pin Mini-din connector that plugs
into the back of the motherboard.
Figure14. Keyboard
2. Direct Entry – A form of input that does not require data to be keyed by someone
sitting at a keyboard. Direct-entry devices create machine-readable data on paper,
or magnetic media, or feed it directly into the computer‘s CPU.
Three Categories of Direct Entry Devices
1. Pointing Devices - An input device used to move the
pointer (cursor) on screen.
 Mouse - The most common 'pointing device' used
in PCs. Every mouse has two buttons and most
have one or two scroll wheels.
Figure15. Mouse

Touch screen- A display screen that is sensitive to the touch of a finger or
stylus. Used in myriad applications, including ATM machines, retail pointof-sale terminals, car navigation and industrial controls. The touch screen
became wildly popular for smart phones and tablets.
Figure16. Touch Screen Devices
47

Light Pen - A light-sensitive stylus wired to a video terminal used to draw
pictures or select menu options. The user brings the pen to the desired
point on screen and presses the pen button to make contact.
F
i
Figure17. Light Pen

Digitizer Tablet - A graphics drawing tablet used for sketching new
images or tracing old ones. Also called a "graphics tablet," the user
contacts the surface of the device with a wired or wireless pen or puck.
Often mistakenly called a mouse, the puck is officially the "tablet cursor."
Figure18. Digitizer Tablet
2. Scanning Devices- A device that can read text or
illustrations printed on paper and translates the
information into a form the computer can use.
Figure19. Image scanner
Figure20. Bar Code Reader
48
3. Voice- Input Devices - Audio input devices also known as speech or voice
recognition systems that allow a user to send audio signals to a computer for
processing, recording, or carrying out commands. Audio input devices such as
microphones allow users to speak to the computer in order to record a voice
message or navigate software.
Figure 21. Microphones
Output Devices
1. Computer Display Monitor- It displays information in visual form, using text and
graphics. The portion of the monitor that displays the information is called the
screen or video display terminal.
Types of Monitor
a. CRT Monitors - Cathode Ray Tubes (CRT) were the only type of displays for use
with desktop PCs. They are relatively big (14" to 16" deep) and heavy (over 15
lbs).
Figure22. Types of Monitor
b. LCD Monitors – Liquid Crystal Display (LCD) technology has been used in
laptops for some time. It has recently been made commercially available as
monitors for desktop PCs.
49
c. LED Monitors (Light Emitting Diode) - A display and lighting technology used in
almost every electrical and electronic product on the market, from a tiny on/off
light to digital readouts, flashlights, traffic lights and perimeter lighting.
2. LCD Projectors- utilize two sheets of polarizing
material with a liquid crystal solution between them. An
electric current passed through the liquid causes the
crystals to align so that light cannot pass through them.
Each crystal, therefore, is like a shutter, either allowing
light to pass through or blocking the light.
FFigure23. LCD Projector
3. Smart Board - A type of display screen that has a touch sensitive transparent
panel covering the screen, which is similar to a touch screen.
Figure24. Smart Board
4. Printer - A device that prints text or illustrations on paper.
Types of printer
a) Ink-Jet or Bubble-Jet Printer - spays ink at a sheet of paper. Ink-jet printers
produce high-quality text and graphics.
b) Laser Printer - Uses the same technology as copy machines. Laser printers
produce very high quality text and graphics.
c) LCD and LED Printer- Similar to a laser printer, but uses liquid crystals or lightemitting diodes rather than a laser to produce an image on the drum.
d) Line Printer - Contains a chain of characters or pins that print an entire line at
one time. Line printers are very fast, but produce low-quality print.
50
Figure 28.Types of Printer
(e) Thermal Printer- An inexpensive printer that works by pushing heated pins
against heat-sensitive paper. Thermal printers are widely used in calculators and
fax machines.
5. Speakers - Used to play sound. They may be built into
the system unit or connected with cables. Speakers allow
you to listen to music and hear sound effects from your
computer.
Figure 29.Speaker
What is a Storage Device?
Aside from the devices attached on a PC, there are also the so called storage
devices that perform a special task in computing system. Storage device is any
apparatus for recording computer data in a permanent or semi-permanent form.
51
Figure 30.Storage Devices
Types of storage devices
Floppy diskette- is a random access, removable data storage medium that can be
used with personal computers. The term usually refers to the magnetic medium
housed in a rigid plastic cartridge measuring 3.5 inches square and about
2millimeters thick. Also called a "3.5-inch diskette," it can store up to 1.44 megabytes
(MB) of data.
Compact disc (CD) – also called optical disc is a nonmagnetic, polished metal disk
used to store digital information. The disc is read by the CD- ROM.
Digital Versatile Disc (DVD)- an optical disc technology with a 4.7 gigabyte storage
capacity on a single-sided, one-layered disk, which is enough for a 133-minute
movie.
Jump drive and USB flash drive- is a plug-and-play portable storage device that
uses flash memory and is lightweight enough to attach to a key chain. A USB drive
can be used in place of a floppy disk, Zip drive disk, or CD.
Hard drive- is the main, and usually largest, data storage device in a computer.
The operating system, software titles and most other files are stored in the hard disk
drive.
52
LS-120- is a drive which supports a special floppy diskette which can store up to
120MB of information as well as being backwards compatible and still supporting the
standard 1.44MB floppy diskettes.
Zip drive-is a small, portable disk drive used primarily for backing up and archiving
personal computer files.

NETWORK
A network consists of two or more computers that are linked in order to share
resources (such as printers and CD-ROMs), exchange files, or allow electronic
communications. The computers on a network may be linked through cables,
telephone lines, radio waves, satellites, or infrared light beams.
There are three basic types of networks which includes the following:


Local Area Network (LAN)
Wide Area Network (WAN)
Local Area Network
A Local Area Network (LAN) is a network that is confined to a relatively small
area. It is generally limited to a geographic area such as a writing lab, school, or
building. Rarely are LAN computers more than a mile apart.
In a typical LAN configuration, one computer is designated as the file server. It
stores all of the software that controls the network, as well as the software that can
be shared by the computers attached to the network. Computers connected to the
file server are called workstations. The workstations can be less powerful than the
file server, and they may have additional software on their hard drives. On most
LANs, cables are used to connect the network interface cards in each computer.
Wide Area Network
Wide Area Networks (WANs) connect larger geographic areas, such as
Florida, the United States, or the world. Dedicated transoceanic cabling or satellite
uplinks may be used to connect this type of network.
Networking Devices
Consist of, but are not limited to non-local printers, workstations, servers,
webcams, data loggers, instruments, dial-in devices, and, in general anything that
requires an Ethernet connection. These devices are supported on a best-effort basis
limited by the staffing and equipment level available.
57
Hub is a small, simple, inexpensive device that joins
multiple computers together. Many network hubs
available today support the Ethernet standard. Other
types including USB hubs also exist, but Ethernet is
the type traditionally used in home networking.
Ethernet switch is a device that gathers the signals
from devices that are connected to it, and then
regenerates a new copy of each signal.
Bridge is a device filters data traffic at a network
boundary. Bridges reduce the amount of traffic on a LAN
by dividing it into two segments.
Routers are small physical devices that join multiple networks
together.
Network
gateway is
an internetworking system
capable of joining together two networks that use
different base protocols. A network gateway can be
implemented completely in software, completely in
hardware, or as a combination of both.
Modem is a contraction of the terms modulator and
demodulator. Modems perform a simple function:
They translate digital signals from a computer into
analog signals that can travel across conventional
phone lines. The modem modulates the signal at the
sending end and demodulates at the receiving end.
58
Network interface is a device that connects a client computer, server, printer or
other component to your network. Most often, a network
interface consists of a small electronic circuit board that is
inserted into a slot inside a computer or printer. Alternatively,
some computers, printers, or other services include network
interfaces as part of their main circuit boards (motherboards).
Network firewall protects a computer network from
unauthorized access. Network firewalls may be
hardware devices, software programs, or a
combination of the two. Network firewalls guard an
internal
computer
network
(home,
school,
business intranet) against malicious access from the
outside. Network firewalls may also be configured to
limit access to the outside from internal users.
Direction: Identify what is being described in the following sentences and write your
answer on a separate sheet of paper.
1. It protects a computer network from unauthorized access.
2. Type of network that connect larger geographic areas, such as Florida, the
United States, or the world.
3. This is an internetworking system capable of joining together two networks
that use different base protocols.
4. It is consists of two or more computers that are linked in order to share
resources (such as printers and CD-ROMs), exchange files, or allow
electronic communications.
5. They translate digital signals from a computer into analog signals that can
travel across conventional phone lines.
6. It is a device that connects a client computer, server, printer or other
component to your network.
7. A device filters data traffic at a network boundary.
8. It is a device that gathers the signals from devices that are connected to it,
and then regenerates a new copy of each signal.
9. It is a small, simple, inexpensive device that joins multiple computers
together.
10. Type of network that is confined to a relatively small area.
59
Now, that you are done with the introduction of network as well as the
networking devices, to enlighten your understanding and knowledge have some
more readings about it thru books and other resources. You should consider the
following topics for research:
1. Different types of Network Topology
2. Common networking tools

SAFETY PRECAUTIONS
Personal Protective Equipment - It refers to protective clothing, helmets, goggles,
or other gear designed to protect the wearer's body or clothing from injury by
electrical hazards, heat, chemicals, and infection, for job-related occupational safety
and health purposes.
PPE can also be used to protect the working environment from pesticide
application, pollution or infection from the worker (for example in a microchipfactory).
It is important that students and teachers during their laboratory period should
be required to use personal protective equipment. Some of these are:
65

Goggles A large spectacles, with
shields around the rims, for protecting
the eyes from dust, excessive light,
wind, etc.

Rubber Sole A special type of shoes
used to prevent electrical shock and for
waterproofing and insulating purposes.

Apron A garment worn over the front
of the body as a protection for one‘s
cloth.

Face Mask A covering for the face to
prevent the inhaling or absorbing dust
and other chemicals

Gloves The covering material with a
separate sheath for each finger used
for hand protection.
Anti-Static and Safety Precautions
The little shock you experience while you are walking across a carpeted floor
or when you touched a door knob, table, counter or even another person is a result
of static electricity. Static electricity is the discharge of electricity between two
objects with different electrical potential. Humans can't feel a static shock until it is
several thousand volts strong, but it takes less than 30 volts to fry a sensitive
computer component, such as a stick of RAM or a processor.
That's why computer technicians and home computer builders have to guard
their computers against the deadly ravages of static electricity, as well as take steps
to avoid injury.

SYSTEM’S SPECIFICATION
Whenever you purchase software or hardware for your computer, you should
first make sure your computer supports the system requirements. These are the
necessary specifications your computer must have in order to use the software or
hardware. For example, a computer game may require your computer to have
Windows XP or later, a 2.0 GHz processor, 512 MB of RAM, a 64 MB graphics card,
and 500 MB or hard drive space. If your computer does not meet all of these
requirements, the game will not run very well or might not run at all.
It is just as important to check system requirements for hardware devices. For
example, if you buy a printer, it may require either Windows XP or Mac OS X 10.3 or
later. It may also require a USB port and 80 MB of available hard drive space. If your
computer does not have any USB ports, you will not be able to physically connect
the printer. If your machine does not have Windows XP or Mac OS X 10.3 or later,
the printer drivers may be incompatible with your operating system. This means your
computer will be unable to recognize the printer.
Most hardware and software products have the system requirements printed
on the side or bottom of the product packaging. When you are shopping for
computer software or hardware, it is a good idea to first find out exactly what your
system's specifications are and write them down on a piece of paper. The important
information to record includes:
1. Operating System (i.e. Windows XP, SP 2 or Mac OS X 10.3.8)
2. Processor Speed (i.e. Pentium 4, 3.2 GHz or Power PC G5, 2.0 GHz)
3. Memory, a.k.a. RAM (i.e. 512 MB)
4. Graphics Card (i.e. ATI Radeon 9800 w/ 256 MB video memory)
5. Hard Disk Space (i.e. 80 GB available)
6. I/O Ports (i.e. USB, Firewire, Serial, Parallel, SCSI, VGA, DVI ports)
By recording these specifications from your computer, you will be able to
make sure your computer supports the products you are buying. In terms of
installation, systems‘ specification is a big consideration in order for a computer to
run and work properly for the most efficient way it could be.
In broad terms, the performance of a computer depends on four factors: the
speed and architecture of its processor or "central processing unit" (CPU), how much
random access memory (RAM) it has, its graphics system, and its internal hard drive
speed and capacity. Also of importance to most users will be the specification of
its Internet connection. Most computer users and in particular those working with a
lot of photographs, music files or videos should also think about the most
suitable storage devices they will need in order to keep and back-up all of their
valuable data.
69
Processor speed and architecture
The speed of a computer's processor chip (technically known as its "clock
speed") in measured in gigahertz (GHz), with the fastest modern processors
currently running at up to 4.7GHz. However, for most computing tasks, including web
browsing, sending e-mails, word processing and spreadsheet work any processor
running at 1GHz or more remains perfectly sufficient.
For applications such as video editing, 3D graphics work and (for the majority
of "power users") playing computer games, higher processor speeds is highly
required. CPU performance is now determined by far more than raw speed alone.
Intel made this very clear when it introduced its system of processor numbers. These
provide an indication of a processor's "architecture", "cache" and "front side bus
(FSB) speed" in addition to its clock speed.
The architecture of a processor is the most important factor to determine its
performance, and refers to its basic design and complexity. Some processors are
simply more sophisticated than others, with Intel (for example) producing "basic"
processors called Celerons and Pentiums, as well as more powerful processors
under its "Core" processor family. The later include the Core 2, Core i3, Core i5 and
Core i7, with the last of these being the most powerful.
In addition to clock speed and architecture, a processor's cache and front side
bus (FSB) speed also determine a computer's overall power. Cache is a form of very
fast memory integrated into the processor chip, and used to store up instructions
(work for the processor) so that it has to slow down as little as possible between
tasks. Cache is measured in megabytes (MB), with (for example) low-end Celeron
processors having as little as 0.25MB of cache (256KB), and high-end Itaniums
having up to 24MB. The simple message is, the more cache the better- though high
levels of cache still come at a very significant price.
Front side bus (FSB) speed is a measure of how fast a microprocessor
communicates with the computer's main circuit board (or "motherboard") into which it
is physically connected. Again, the higher the measure the better for overall
performance, with FSB speeds currently ranging from 533MHz (still perfectly
sufficient for the vast majority of applications) up to 1600 MHz.
RAM
To a large extent, the more RAM a computer has the faster and more
effectively it will operate. Computers with little RAM have to keep moving data to and
from their hard disks in order to keep running. This tends to make them not just slow
in general, but more annoyingly intermittently sluggish.
70
RAM is measured in megabytes (MB) and gigabytes (GB), as detailed on
the storage page. Just how much RAM a computer needs depends on the software it
is required to run effectively. A computer running Windows XP will usually function
quite happily with 1GB of RAM, whereas twice this amount (ie 2GB) is the realistic
minimum for computers running Windows 7.
Graphics system
A computer's graphics system determines how well it can work with visual
output. Graphics systems can either be integrated into a computer's motherboard, or
plugged into the motherboard as a separate "video card". Graphics systems
integrated into the motherboard (also known as "onboard graphics") are now quite
powerful, and sufficient for handling the requirements of most software applications
aside from games playing, 3D modeling, and some forms of video editing.
Any form of modern computer graphics system can now display highresolution color images on a standard-sized display screen (ie any monitor up to
about 19" in size). The more sophisticated graphics cards now determines how well
a computer can handle the playback of high definition video, as well as the speed
and quality at which 3D scenes can be rendered. Another key feature of separate
graphics cards is that most of them now allow more than one display screen to be
connected to a computer. Others also permit the recording of video.
As a basic rule, unless a computer is going to be used to handle 3D graphics
or to undertake a significant volume of video editing or recording, today there is little
point in opting for anything other than onboard graphics (not least because separate
graphics cards consume quite a lot of electricity and create quite a lot of heat and
noise). Adding a new graphics card to a computer with onboard graphics is also a
very easy upgrade if required in the future.
Hard Drive Speed and Capacity
Today 40GB is an absolute minimum hard drive size for a new computer
running Windows 7, with a far larger capacity being recommended in any situation
where more than office software is going to be installed. Where a computer will
frequently be used to edit video, a second internal hard disk dedicated only to video
storage is highly recommended for stable operation. Indeed, for professional video
editing using a program like Premiere Pro CS5, Adobe now recommend that a PC
has at least three internal hard disks (one for the operating system and programs,
one for video project files, and one for video media).
Two key factors determine the speed of traditional, spinning hard disks. The
first is the rotational velocity of the physical disk itself. This can currently be 4200,
5400, 7200, 10000 or 15000 rpm (revolutions per minute). The faster the disk spins,
71
the quicker data can be read from or written to it, hence the faster the disk the better
(although faster disks consumer more power, make more noise, and generate more
heat). Most desktop hard disks run at either 5400 or 7200 rpm, whilst most laptop
hard disks run at 4200 or 5400.
The second key factor that determines performance of a traditional, internal
hard disk is the interface used to connect it to the computer's motherboard. Three
types of interface exist: Serial Advance Technology Attachment (SATA), which is
the most modern and now pretty much the norm on new PCs; Integrated Device
Electronics (IDE) (also known as UDMA), which is a slower and older form of
interface, and finally SCSI, which happens to be the oldest but in it most modern
variant is still the fastest disk interface standard.
Now, in order for you to better understand the topics under system‘s
specification, dig deep into your mind and answer the following essential questions:
1. In your point of view, describe system specification?
2. How does it affect the performance of the computer?
3. What is the relevance of understanding system specification in computer
hardware servicing?
4. Why do you think that system specification is one of the most important
considerations during installation?
72
INSTALLATION OF HARDWARE COMPONENTS AND OTHER PERIPHERALS
One of the basic skills that you must acquire in computer hardware servicing
is to independently assemble and disassemble a personal computer or simply setting
up a PC. After familiarizing with all the tools, devices, peripherals and safety
precautions I believe that you are now ready to gain another experience in CHS by
going through this lesson.
Personal Computer Disassembly
Before starting computer disassembly, make sure you have the tools you
need and they're all close by and handy and be sure to have a container to keep the
screws in so you have them when you want to put things back together.
Step1. Unplugging - The first thing you do is to unplug every cable that is plugged
in to your computer. That includes the cables such as Power, USB, Mouse,
Keyboard, Internet, Ethernet, Modem, AM\FM Antenna, Cable TV, etc. Just unplug
all the cables for safety purposes.
Now that your computer is fully unplugged, move your PC to a clean work
space.
Step2.Opening the Outer Shell/Case- First, unscrew the four screws at the back of
the computer. On most computer cases, there will be large knobs that you can
unscrew by hand or by screw driver on the back-right side of the computer. The left
side has small screws because on that side you can't access much on the inside.
Figure 32. Screw at the back of computer chasis
Once the screws are removed, you can remove the side panels. On most
computers, they just slide off. Start with the left side panel (the side that once had
the knobs), slide it towards the back of the computer. Now you can remove the left
panel. Just like the other side, slide it towards the back of the computer.

NOTICE:
If you are working on a carpet, about every five minutes touch something that is
grounded (Sink faucet / pipe, wire coming from the ground part of a wall outlet). This
is done so you do not shock your motherboard or other parts.
Step3. Removing the System Fan - First, unplug the fan from the motherboard.
You can find the plug by following the wire from the fan. It should be labeled
"SYS_FAN1". Next, you will have to unscrew the fan from the outside. You should
now be able to lift the fan out of the PC.
System Fan
Figure 34. Removing the system fan
Step4. Removing the CPU Fan- The CPU fan is located right on top of the CPU
heat sink, which is a large piece of metal with fins on the top. The CPU fan plugs into
the motherboard in an awkward place, that is hard to access. But just follow the
wires and you should easily find it. It is labeled "CPU FAN1". To remove the fan from
the heat sink, remove the four screws securing it in place.
74
CPU Fan
Figure 35. Removing the CPU fan
Step5. Power Supply - The first thing to do is unplug every wire coming from the
power supply. You must disconnect the motherboard (very large connector/plug),
CD/DVD drive(s) power, internal hard drive power and portable hard drive slot
power.
Once everything is unplugged,
unscrew the four screws holding the power
supply in place, on the back of the
computer. Next, push the power supply
from the outside, and then lift it out.
Figure36. Unscrew the power supply
Step6. CD/ DVD Drive(s)-First, unplug the ribbon from the back of the drive. Once
that is completed, pull on the tab
securing the drive in place, then
push it out from the inside.
CD / DVD
Drive
Figure 37. Location of CD / DVD Drive
75
Step7. Hard Drive - First, unplug the connector at the back of the slot, and unplug
the other end from the motherboard. Also unplug the SATA cable from the
motherboard and the hard drive. The portable hard drive slot is secured the same
way the CD/DVD drive is, with a tab. Pull on the tab, then slide the slot out.
Figure 38. Unplugging the Hard Drive connector
To remove the hard drive from the side of the slot, unscrew the four screws securing
it in place. You must be very careful not to drop the hard drive, since it is very
delicate!
Figure 39. Removing the hard drive from the side of the slot
Step8. Memory (RAM) - To remove the RAM, push down on both tabs holding the
RAM in place, which are located at both ends of the RAM.
Figure 40. Removing the Memory
76
Step9. Motherboard - The motherboard has seven screws holding it to the frame,
which are indicated by large white circles around them. Remove them and then lift
the motherboard out of the frame.
Figure 41. Removing the Motherboard
Personal Computer Assembly
Now that you have the skills in disassembling a personal computer, Ibelieve
that you are ready to take another step of this module which is assembling a
personal computer. All you need to do is to follow the step by step procedures
provided in this module.
Step 1. Prepare your workplace
1. Take Inventory:
Before you start, take an inventory of your parts. Do not begin assembling
your computer if you don't have everything you need. Begin the step-by-step process
once you are ready with everything you need.
Figure 42. Take inventory of the Different Computer Parts
2. Make Space, Make Time:
77
Building a PC takes up space - about a dining room table worth. So make
sure you have plenty of working room and a few hours to proceed with minimal
interruption. Work on a flat, stable table top surface, or bare floor, where you have
room to layout all of the items.
3. Prepare Grounding Protection:
Use an inexpensive antistatic wrist strap. Make sure you are wearing your
antistatic wrist strap correctly (it does you no good at all if you do not wear it!), and
you are ready to proceed. Look at Figure 43 for details.
Figure 43. Wearing the Anti- static Wrist Strap Correctly
4. Have the Drivers Ready:
Assuming you have another internet connected PC, download the latest
drivers from the vendors' websites for each component you will be
installing. Sometimes drivers are updated between the time the component was
manufactured and the time you are installing it. It is always best to have the
latest. Copy them to a CD for easy access.
Step 2. Prepare the Motherboard
1. Great care should be taken when
installing the motherboard. First, take the
board out of its packaging and put it on
top of the antistatic bag it came in (see
Figure 45). Remember, you always want
to safeguard your components from
potentially hazardous static electricity
(wear your strap).
Figure 44. Motherboard in an Antistatic Bag
2. Before you secure the motherboard onto the PC case/chassis, inspect it
carefully for any visible defects.
78
3. Next, review the motherboard manual, to make sure you are familiar with the
motherboard layout and understand which socket is which. Manuals are
extremely helpful, usually easy to read, and include illustrations. Below you
can find instructions on how to install the processor, the heat sink and the
memory modules on the motherboard. You should not place the motherboard
in the computer case until you are told to do so.
Step 3. Install the CPU
1. Use the unlocking mechanism to
open the CPU socket which is
usually a lever.
2. Carefully line up the pins and
place the chip in its socket; it will
fit only when oriented the proper
way. An arrow or a missing pin on
one corner of the chip will show
you how to line things up.
3. Align Triangular CPU and socket
key marks as shown in Figure 46.
4. Lower the lever to lock the CPU
into place.
Figure 45. Install CPU
Step 4. Install the CPU Heat Sink
1. Follow the manufacturer's directions to install the heat sink and the fan that
will cool the processor. If you bought an OEM CPU and a separate heat sink,
you may need to spread a thin layer of the thermal grease that came with the
heat sink over the chip to ensure proper transfer of heat (some heat sinks
come with this grease already applied).
Figure 46. Install CPU Heat Sink
79
3. Attach the clip that holds the heat sink in place keeping in mind that it may
require a fair amount of force. Again, follow the instructions that came with the
heat sink. They will show you how to fit it correctly. If you are in doubt, you
can visit the manufacturer's website for more information.
4. Plug the CPU fan's power connector into the proper connector on the
motherboard.
Step 5. Install Memory (RAM Modules)
In order to install the memory
modules, insert them into the proper
sockets (Figure 48) and push down
firmly but evenly until the clips on both
sides of the socket pop into place. If
your motherboard supports dualchannel memory, consult the user
manual to determine which pairs of
RAM sockets you should use. The
motherboard and the CPU are the
brain and nerve center of your PC, so
selecting these components is the
most important decision you'll make.
Figure 47. Install RAM Memory
Step 6. Place the motherboard into the case
1. Some PC cases have a removable motherboard tray. If yours does, remove the
screws holding it in place and pull it out of the case (Figure 49).
Figure 48. Remove Motherboard Tray
2. Note the pattern of the holes in your motherboard (Figure 50), and screw brass
standoffs into the motherboard tray or into the PC case in the correct locations
(ALWAYS check the manual and follow their instructions to the letter).
80
Figure 49. Screw Brass Standoffs Into the Motherboard
3. Check the layout of the sockets on the motherboard, and confirm that the ports on
your motherboard's back panel match the holes on the case's Input/Output (I/O)
shield that is installed in your case. If necessary, remove the old I/O shield by
tapping it firmly a few times with the butt-end of a screwdriver, and then replace it
with the shield that came with the new motherboard.
4. Carefully position the motherboard on top of the brass standoffs (Figure 51), line
up all the holes, and use the screws that accompanied the case to fasten down the
motherboard. If you are using a removable tray in your system, slide the tray and
motherboard back into the case and then secure the tray.
Figure 50. Case‘s I /O Shield
Figure 51. Mount the Motherboard
81
Step 7. Connect the Power Supply
Making the proper connections is crucial to successfully assembling your PC
system. Fortunately, manufacturers provide color-coded power cables and unique
connector shapes to make the job easy.
1. First, plug the large ATX power connector (Figure 53) from your power supply into
the matching port on your motherboard. Look Figure X for details.
2. Locate the smaller, square processor power connector (Figure 54) (you cannot
miss it - it is the one sprouting the yellow and black wires) and attach it to the
motherboard. Note: your connector is usually located near the processor. As
always, refer to your motherboard's manual for the exact locations.
3. Use your motherboard user manual and find the description about front-panel
connectors.
Figure 53. Large ATX Connector
Figure 52. Connect the ATX Power in the Motherboard
Figure 53. Square Processor Power Connector
82
NOTE:
You are going to be doing work that requires attention to detail and can be quite
frustrating if you do not go into it with the right attitude.
4. Attach each of the tiny leads from the power and reset switches (Figure 56), the
hard-disk activity lights, the PC speaker, and any front-panel USB and FireWire ports
to the corresponding pin on your motherboard. The needle-nose pliers are useful for
manipulating small pieces.
Figure 54. Connect the different Leads
Step 8. Install Graphics / Video Cards
1. Begin by removing the backplane cover from the AGP or PCI Express X16
slot (the metal piece where the monitor connector will emerge) (Figure 55).
Figure 55. Remove the backplane cover
2. Install the graphics board in that slot, and then secure the card with a screw
(Figure 56).
83
Figure 56. Install the Graphics Board
Step 9. Install Internal Drives
Now it is time to install your drives. This is an easy process, but it requires attention
to detail.
1. Make any necessary changes to jumpers on the drives before mounting them
in the case. A two-drive system (one or two SATA (Serial ATA- is a standard
hardware interface for connecting hard drives and CD/DVD drives to a
computer)
hard
drives,
plus
one
parallel
ATA
(Advanced Technology Attachment) optical drive, for example) is easy to set
up; the SATA drives are jumper less, and the optical drive can be set as
master on its own parallel ATA channel. Many cases have removable drive
rails or cages to house drives.
2. Use the included screws to attach your drives to the rails or cage, and slide
them into the case. For externally accessible drives such as a DVD recorder,
you can save time by installing one drive rail and sliding the drive in for a test
fitting to make sure that its front is flush with the case (Figure 57).
3. When the drives are installed, connect power and data cables to each one.
Parallel ATA drives use wide, flat data cables that can be installed only in the
correct way. Floppy drives use a similar but smaller cable; SATA drives use a
thin, 1cm-wide data cable. SATA drives use a new type of power connector
that many power supplies don't come with. Fortunately, many motherboards
ship with adapters for converting a standard four-pin power connector to a
SATA power connector (Figure 57).
84
Figure 57. Attach your devices
Figure 58. Connect Power Connector
Step 10. Install the Add- in Cards
1. For each add-in card, you must choose a free PCI slot.
1. Remove its backplane cover to allow access from the rear of the case.
3. Carefully position the card above the slot, and press down firmly to seat the
card (Figure 59).
4. Secure the card with a screw.
85
Figure 59. Add- in Cards
Many motherboards have additional sound connectors or ports housed on
small add-in boards. Some of these plug into slots on the motherboard; others screw
into the back of the case in place of slot covers. Usually the additional ports are not
essential to your PC's operation. For example, if you install a sound card, you do not
need connectors to the motherboard's built-in sound chip. Check your motherboard
manual to determine what each of these boards does.
Connecting Peripherals of a Personal Computer
When attaching hardware and peripherals of the computer, ensure that they
are connected to the correct locations or ports. For example, some mouse and
keyboard cables use the same type of PS/2 connector. So, you must know first the
different ports that can be found in the back panel of the computer.
Keep in mind:
1. When attaching cables, never force a connection.
2. Plug in the power cable after you have connected all other
cables.
Steps in Connecting Peripherals of a PC
Step 1.Attach the monitor cable to the video port.
Step 2.Secure the cable by tightening the screws on the connector.
Step 3.Plug the keyboard cable into the PS/2 keyboard port.
Step 4.Plug the mouse cable into the PS/2 mouse port.
Step 5.Plug the USB cable into a USB port.
Step 6.Plug the network cable into the network port.
Step 7.Plug the power cable into the power supply.

INSTALLING OPERATINFG SYSTEM
Before the installation process undertake, a technician must be aware of the
minimum requirements of a computer hardware that is compatible with the operating
system to be installed. Following the systems‘ requirements means an efficient
computer system. The list below shows the windows XP minimum requirements for
installation:
 Pentium 233 Mhz or compatible processor or faster; 300MHZ or faster
recommended
 64MB of RAM minimum; 128MB or more recommended
 4.3GB hard hard disk space or more
 CD-ROM or DVD-ROM
 Super VGA (800X600) or higher-resolution monitor
 Keyboard and mouse
Windows XP Installation
1.
Insert the Windows XP CD-ROM and reboot the computer

If you see a message about press any key to boot the CD, do so now.
Otherwise, you will see a message about Setup inspecting your system.
Figure 62. Boot from CD
91
2.
MS-DOS portion of Setup begins


In the first stage of setup; you will see a series of blue and gray MS-DOSbased screens.
In the first step, you will be asked to press F6 if you need to install any thirdparty or RAID drivers.
Figure 63. Windows Set-up
3. Welcome to Setup


Finally, Setup begins. In this step, you can set up XP, launch the Recovery
Console (another, more complicated system recovery tool), or quit.
Press ENTER to continue Setup, and it will examine your hard drives and
removable disks.
Figure 64. Welcome to Set-up
92
4. Read the license agreement


Next, you'll have to agree to Microsoft's complex licensing agreement. Among
the highlights: You don't actually own Windows XP and you can only install it
on one PC.
Hit F8 to continue.
Figure 65. License and Agreement
5. Choose an installation partition



This crucial step lets you choose where to install XP.
On a clean install, you will typically install to the C: drive, but you might have
other ideas, especially if you plan to dual-boot with 9x.
Setup will show you all of your available disks (in this case, just one) and let
you create and delete partitions as needed. So, for example, if you have one
disk, but would like to create two partitions, one for XP and one for your data,
you can do that here.
Figure 66. Choose an Installation Partition
93
6. Select the file system


If you created a new partition, or wish to change the file system of an existing
partition, you can do so in the next step. NTFS (New Technology File System)
file system is more secured than FAT (File Allocation System).
Regardless of which file system you choose, be sure to select one of the
"quick" format options (the top two choices), if you do need to format, since
these
will
work
much
more
quickly
than
a
full
format.
Figure 67. Select the File System
7. Optionally format the partition


If you did choose to change or format the file system, this will occur next.
First, you'll be asked to verify the format. If you're installing XP on a system
with more than one partition, especially one that still holds your data on one of
the partitions, be sure you're formatting the correct partition.
Hit F to continue, and a yellow progress bar will indicate the status of the
format. When this is complete, Setup will again examine your disks, and
create a list of files to copy.
Figure 68. Optionally Format the Partition
94
8. Setup folder copy phase and reboot
 Setup will now copy system files to the system/boot partition(s) you just
created. This will allow the PC to boot from the C: drive and continue Setup in
GUI mode.
 When the file copy is complete, Setup will initialize and save your XP
configuration.
 It will then reboot your PC.When the system reboots, you will probably see the
"Press any key to boot from CD" message again. If this happens, do not press
a key: Setup will now boot from your C: drive. In the event that you cannot
prevent the CD-based Setup from reloading, eject the CD and reboot. Setup
will ask for the CD when needed.
Figure 69. Setup Folder Copy Phase
9. GUI Setup begins


Once the system reboots, you will be presented with the GUI Setup phase,
which is much more attractive than the DOS-mode phase. As you progress
through GUI Setup, you can read promotional information on the right side of
the screen about XP.
Next, your hardware devices are detected. This could take several minutes.
Figure 70. GUI Setup
95
10. Regional and language Options


In the first interactive portion of GUI Setup, you can choose to customize the
regional and language settings that will be used by XP, as well as the text
input language you'd like. Users in the United States will not normally need to
change anything here.
Click Next to continue.
Figure 71. Regional and Language Options
11. Personalize your software


Now, enter your name and your company.
The name you enter is not the same as your user name, incidentally, so you
should enter your real name here (i.e. Rosalie Lujero or whatever).
Click Next to continue.
Figure 72. Software Personalization
96
12. Enter your product key


Now you must enter the 25-character product key that is located on the
orange sticker found on the back of the CD holder that came with Windows
XP. You cannot install XP without a valid product key. Later on, you will be
asked to activate and optionally register your copy of Windows XP. A product
key can be used to install XP on only one PC.
Click Next to continue.
Figure 73. Enter Product Key
13. Enter a computer name and administrator password

In the next phase of Setup, you can create a name for your computer (which
is used to identify it on a network) and, optionally in Pro Edition only, a
password for the system Administrator, the person who controls the PC (this
will generally be you, of course).
Figure 74. Enter Computer Name and Administrator Password
97
14. Supply your date and time settings


Next, you can supply the date and time, which are auto-set based on
information in your BIOS, and the time zone, which is irritatingly set to PST,
which is where Microsoft is. Change these as appropriate.
Click Next to continue.
Figure 75. Enter Date and Time Settings
15. Network setup

If you have a networking card or modem, Setup now install the networking
components, which include the client for Microsoft networks, File and Print
Sharing, the Quality of Service (QoS) Packet Scheduler, and the TCP/IP
networking protocol by default.
Figure 76. Network Set-Up
98
16a. Choose networking settings


In this phase, you can choose to keep the default settings (recommended) or
enter custom settings.
Note that XP doesn't include the legacy NetBEUI protocol out of the box.
If you want to use this protocol, you will need to install it later from the XP
CD-ROM.
Click Next to continue.
Figure 77. Choose Networking Settings
Windows XP Professional only:
16b. Enter workgroup or domain information


In Windows XP Professional only, you will be able to select a workgroup or
domain name next. Home Edition doesn't work with Windows domains,
however, and Setup will automatically supply the workgroup name MSHOME,
which you can change later. The default workgroup name in XP Pro is,
imaginatively, WORKGROUP.
Click Next to continue.
Figure 78. Enter Workgroup or Domain Information
99
17. Set-up completion


From this point on, Setup will continue to completion without any further need
for interaction. Setup will now copy files, complete installation, install your
Start Menu items, register system components, save settings, remove any
temporary files needed by Setup, and then reboot.
Again, you will probably see the "Press any key to boot from CD" message on
reboot. If this happens, do not press a key, and your new XP install will boot
up. You can remove the XP Setup CD now.
Figure 79. Set- Up Completion
18. First boot

You‘ll be greeted by the XP splash screen on first boot (this actually appears
briefly when you rebooted into GUI Setup as well).The splash screens for XP
Pro and Home are subtly different.
Figure 80. First Boot
100
19. Change display settings



Users with CRT monitors and some LCDs (such as laptops and flat panel
displays) will see a Display Settings dialog appear, which asks whether you'd
like XP to automatically set the resolution. This will generally change the
resolution from 800 x 600 to 1024 x 768 on a CRT monitor, or to the native
resolution of an LCD display.
Click OK and let XP change the resolution. Then, accept the settings if the
screen display changes and can be read. If you can't see the display, it will
time out after 30 seconds and return to the sub-optimal 800 x 600 resolution.
Click OK to accept the screen resolution change.
Figure 81. Change Display Settings
20. Welcome to Microsoft Windows


Now, you are presented with XP's "Out of Box Experience," or OOBE, which
presents a silly wizard to guide you through the final set up of your PC.
Click Next to continue.
Figure 82. Welcome to Microsoft Windows
101
21. Network setup



In the opening OOBE phase, you are asked to set up your network/Internet
connection, which is required for activation and registration. If you selected
the default networking configuration during Setup and know it will work
(because you're connected directly to a cable modem, perhaps, or are on a
local area network), then select Yes (the default). Otherwise, you can select
No and then Skip.
We'll assume that your network is up and running and select Yes.
Click Next to continue.
Figure 83. Network Set- up
22. Optionally activate and register Windows
 If you selected Yes in the previous step, you are asked if you'd like to
activate Windows XP. This will tie your copy of XP to the current PC semipermanently. Activation requires a connection to the Internet, but you can
perform this step later if you want (and don't worry, XP will annoyingly
remind you of this fact every time you boot the machine until you do so).
Figure 84. Windows Activation
102
23. Set up users




Now, you can set up the user names of the people who will be using the PC.
You will want at least one user (for you), since you shouldn't be logging on as
Administrator. Curiously, each user you do create here has administrative
privileges, however, and no password. You should set up your users correctly
with passwords as soon as possible.
This phase lets you create up to five users. You can create more later, or
manage users, using the User Accounts tool in Control Panel.
Click Finish when done creating users. At this point, OOBE ends and you're
reading to go.
Click Finish again.
Figure 85. Set-up Users
24. Logon to Windows XP for the first time
 Click your name, that account will logon and you'll be presented with the XP
desktop. After you create passwords, however, you'll be asked to enter a
password before you can logon.

BASIC COMPUTER CONFIGURATION SETUP
Configuration is the way a system is set up, or the assortment of
components that make up the system. Configuration can refer to
either hardware or software, or the combination of both.
Basic Input / Output System (BIOS)
The Basic Input Output System, usually referred to as BIOS, is software
stored on a small memory chip on the motherboard.
BIOS instruct the computer on how to perform a number of basic functions
such as booting and keyboard control. BIOS is also used to identify and configure
the hardware in a computer such as the hard drive, optical drive, CPU, memory, etc.
Figure 108. BIOS Set- up
The BIOS is accessed and configured through the BIOS Setup Utility. The
BIOS Setup Utility is, for all reasonable purposes, the BIOS itself. All available
options in BIOS are configurable via the BIOS Setup Utility. The BIOS Setup Utility is
accessed in various ways depending on your computer or motherboard make and
model.
119
BIOS access and configuration on PC systems is independent of
any operating systembecause the BIOS is part of the motherboard hardware. It
doesn't matter if a computer is running Windows 7, Windows Vista, Windows XP,
Linux, Unix, or no operating system at all - BIOS functions outside of the operating
system environment and is no way dependent upon it.
BIOS contain a number of hardware configuration options that can be
changed through the setup utility. Saving these changes and restarting the computer
applies the changes to the BIOS and alters the way BIOS instructs the hardware to
function. The following list shows the things you can do in most BIOS systems:


Device Drivers
Now that you successfully installed the operating system, you‘ll need to
configure the devices such as Video Cards, Network Interface Cards, Sound Cards,
etc by installing the device drivers of each. In many cases, if Windows recognizes
the device, drivers will be installed automatically. In some cases, generic drivers are
installed so that the devices will work properly.
Drivers are small software programs that help the operating system use or
―drive‖ the device. Whenever a device doesn‘t work properly, ask if the proper driver
has been installed.
The procedures listed below describe how to obtain and install drivers for
hardware devices on a Microsoft Windows 2000-based computer.
Step 1: Determine the Hardware Manufacturer
If you do not know the manufacturer of the device for which you want to install the
driver, follow these steps to determine the manufacturer:

 Device Manufacturer
Contact the manufacturer of the device to inquire about how to obtain,
download, and install the latest drivers for the device.
123
 Chipset Manufacturer
Contact the chipset manufacturer of the device to find out how to obtain,
download, and install the latest drivers for the device. It is best to first contact the
manufacturer of the device for the drivers before you contact the chipset
manufacturer.
For example, if your display adapter uses a NVIDIA chipset, first contact the
manufacturer of the display adapter. If you cannot contact the display adapter
manufacturer or if the manufacturer does not have a driver, contact NVIDIA.
Some examples of chipset manufacturers (and their Web sites) include:
 NVIDIA (display adapters)
 PCTEL, Inc. (modems)
 Installation CD or Floppy Disks
If you have the original driver CD or floppy disks that were included with the
computer or device, and if no other source for the drivers is available, use the
original
driver
that
is
included
with
the
computer
or
device.
NOTE: Whenever possible, try to first contact the Original Equipment Manufacturer
(OEM), device manufacturer, or chipset manufacturer to obtain the latest version of
the driver.
Step 3: Install the Driver
 The driver files that you download from the OEM, device manufacturer, or
chipset manufacturer differ depending on how the driver is packaged by the
manufacturer.
 If the file is an executable program, run the program to extract the files. If the
file is in .zip format, you can use a third-party utility such as WinZip to extract
the files. For more information about how to extract the driver files, see the
instructions that are provided by the manufacturer of the driver.
 The driver may use a setup program. The driver package may contain raw
driver files, or it may contain only raw driver files. Some examples include .inf
files, and .sys files. To install the driver, use one of the following methods
as appropriate to your situation.
 Driver with a Setup or Installation Program
If the driver uses a setup or installation program, run the program to install the
driver. For more information about how to do this, see the documentation or contact
the driver manufacturer.

Lesson3. CONDUCT TEST ON THE INSTALLED COMPUTER SYSTEM
In the previous lesson, you were introduced with all the necessary knowledge
and skills on installation of computer devices and operating system. Now, after
executing the correct procedures I am sure that installation is a very easy task for
you. Those skills will be very essential for the next lesson.
In the next phase of your learning it will focus in conducting test on the
installed computer components. After reading all the required topics and performing
the essential skills you must be able to:
 Follow OHS policies and procedures in conducting tests;
 Check circuits and systems being isolated using specified testing procedures;
 Test devices, systems and/or installation to determine its conformity with the
requirements;
 Undertake final inspections on the installed devices, systems to ensure
conformity with the requirements;
 Accomplish technical reports on the tests conducted; and
 Follow procedures in forwarding documentation to appropriate personnel and/or
authority on the test conducted.
TESTING INSTALLED EQUIPMENT / DEVICES (COMPONENTS)
As computer technician you will need a good understanding of the health and
safety regulations from early on in your career, so that you understand the good
practices demanded by law. In particular, you need to:
 report any accidents
 take reasonable care of your own health and safety when moving
heavy components
 not cause any electrical hazards
 make sure that workstations meet safety requirements.
You need to adhere to health and safety regulations as they will help to protect you
and others and will avoid any unnecessary legal action for reckless and unsafe
working practices. If you identify any health and safety problems, you should tell your
line manager or the health and safety representative immediately.
127
The most basic test is to switch the system on to check it starts without errors.
ICT professionals are also likely to use tools and utilities to check that all is well with
the system after an installation.
The Use of Diagnostic Tools in testing installed hardware components and
other peripherals
Diagnostic tools are used to test and diagnose equipment. Diagnostic tools
include the following:
 Digital multimeter is a device that can take many types of measurements. It
tests the integrity of circuits and the quality of electricity in computer
components. A digital multimeter displays the information on an LCD or LED.

A loopback adapter, also called a loopback plug, tests the basic functionality
of computer ports. The adapter is specific to the port that you want to test.

The toner probe, is a two-part tool. The toner part is connected to a cable at
one end using specific adapters, such as an RJ-45, coaxial, or metal clips.
The toner generates a tone that travels the length of the cable. The probe part
traces the cable. When the probe is in near proximity to the cable to which the
toner is attached, the tone can be heard through a speaker in the probe.
Figure 114. Diagnostic Tools
Software Tools
Like hardware tools, there are a variety of software tools that can be used to
help technicians pinpoint and troubleshoot problems. Many of these tools are free
and several come with the Windows operating system.
Disk Management Tools
Software tools help diagnose computer and network problems and determine which
computer device is not functioning correctly. A technician must be able to use a
range of software tools to diagnose problems, maintain hardware, and protect the
data stored on a computer.
128
You must be able to identify which software to use in different situations. Disk
management tools help detect and correct disk errors, prepare a disk for data
storage, and remove unwanted files.
The following are some disk management tools:







FDISK: A command-line tool that creates and deletes partitions on a hard
drive. The FDISK tool is not available in Windows XP, Vista, or 7. It has been
replaced with the Disk Management tool.
Disk Management Tool: Initializes disks, creates partitions, and formats
partitions.
Format: Prepares a hard drive to store information.
ScanDisk or CHKDSK: Checks the integrity of files and folders on a hard
drive by scanning the file system. These tools might also check the disk
surface for physical errors.
Defrag: Optimizes space on a hard drive to allow faster access to programs
and data.
Disk Cleanup: Clears space on a hard drive by searching for files that can be
safely deleted.
System File Checker (SFC): A command-line tool that scans the operating
system critical files and replaces files that are corrupted.
Use the Windows 7 boot disk for troubleshooting and repairing corrupted files.
The Windows 7 boot disk repairs Windows system files, restores damaged or lost
files, and reinstalls the operating system.
Test procedures
A test procedure is a set of steps to guide you through what needs to be done
to thoroughly test the installation. It is designed to help you work more effectively and
to make sure you test everything that needs testing.
Test procedures are created in-house and could include these steps:
1. Gathering test information. The first step is to run the tests required by the
procedure and find out what happens. You should record all the results of your tests
in a log so that you know which pass and which fail, thereby requiring further action.
2. Validating the test information. The next step is to check the data you gathered
from the tests to make sure it is correct. This is usually done by running the tests
again.
3. Responding to test information. This step is important because you need to be
able to recognize when a test shows problems or is successful. For example, if ping
is used to test a network connection then ‗Request timed out‘ shows the test was not
successful.
129
4. Checking specification. The final step is an important end to testing. You need
to check the specification for the installation to make sure that it has been met. For
example, if a user requested an upgrade to make their display run at 1920 x 1200,
then the ICT professionalshould check that the graphics card and screen can do this.
External Visual Inspection
The external visual inspection consists of a quick inspection of the exterior of
the computer, the monitor, the keyboard, any peripherals, and cables. While
performing the visual inspection, make any necessary corrections. To perform the
external visual inspection, perform the following steps:
1. Turn off the computer, the monitor, and all peripherals.
2. Verify that all power cables are properly connected to the computer, the
monitor and peripherals, and their power sources.
3. Verify that the keyboard and mouse interface cables are firmly attached to the
proper connectors on the back of the computer.
 For a PS/2-compatible mouse, the keyboard and mouse interface cable
connectors are identical except for their labels.
 For a serial mouse, the mouse interface cable must be firmly attached
to one of the serial port connectors, and its captive screws must be
secure enough to ensure a firm connection.
4. Verify that network cables (if present) are properly attached.
5. Verify that any devices attached to the serial and parallel port connectors are
properly connected.
 Each of the serial and parallel port interface cables must be firmly
attached to an appropriate connector on the back of the computer as
well as to the interface connector on the device. The captive screws
that secure these connectors at each end of the interface cable must
be secure enough to ensure a firm connection.
6. Verify that the video interface cable is firmly attached to the video connector
on the back panel or to a video expansion card, and also to the connector on
the back of the monitor. For proper connection of the video monitor, see the
documentation for the monitor.
7. Inspect all external monitor controls for any obvious damage or improper
settings. For proper settings of the video monitor controls, see the
documentation for the monitor.
8. Inspect the keyboard to ensure that no keys are sticking. If one or more keys
are sticking, it may be necessary to replace the keyboard.
9. Inspect the exterior of the computer, including all controls and indicators, and
all user-accessible data storage devices for any signs of physical damage.
Does the inspection reveal any problems?
Yes. Proceed to the appropriate procedure in "Removing and Replacing
Parts."
130
No. Proceed to "Observing the Boot Routine."
Observing the Boot Routine
After you have performed an external visual inspection as described in the
previous section, you should boot the system and, while the boot routine is running,
observe the system for any indications of problems.
NOTE: Most of the steps in this procedure require observation of system
functions and indications, some of which can occur simultaneously. It may be
necessary to reboot the system several times to complete all of these steps.
To observe problem indications during the boot routine, perform the following steps:
1. If the system is off, turn on all peripherals and the computer.
2. Check the power supply fan.
Does the fan run normally?
o Yes. Proceed to step 3.
o No. Troubleshoot the system power supply.
3. Watch the <Num Lock>, <Caps Lock>, and <Scroll Lock> indicators on the
upper-right corner of the keyboard. After all three indicators flash momentarily,
and following a long pause (approximately 30 seconds), the Num Lock
indicator should light up and remain on (unless the Num Lock option is set
to Off in
the
System
Setup
program).
Do these indicators flash on and off within approximately 10 seconds after the
boot routine starts?
o Yes. Proceed to step 4.
o No. Troubleshoot the system power supply. If the troubleshooting
procedure indicates that the system power supply is operational,
troubleshoot the memory.
4. During the boot routine, observe the system for any of the following
indications:
o
Beep codes — A beep code is a series of beeps that indicates an error
condition.
o
System error messages — these messages can indicate problems or
provide status information.
o
Diskette-drive and hard-disk drive access indicators — These
indicators light up in response to data being transferred to or from the
drives. If either of these indicators fails to light up during the boot
131
routine, troubleshoot the diskette drive or hard-disk drive subsystem,
as appropriate.
5. Observe the monitor screen for the Diagnostics menu.
Internal Visual Inspection
NOTICE: Before you proceed with the internal visual inspection described in this
section, ensure that the user has saved all open files and exited all open
application programs if possible.
A simple visual inspection of a computer‘s interior hardware can often lead to
the source of a problem, such as a loose expansion card, cable connector, or
mounting screw. To perform the internal visual inspection, perform the following
steps:
1. Turn off the system, including any attached peripherals, and disconnect all the
AC power cables from electrical outlets.
CAUTION: Before beginning to work inside the computer, disconnect the
power supply from the power source and the power supply cables from
the power supply.
2. Remove the computer‘s right side cover.
CAUTION: The heat sink assembly can get extremely hot during system
operations. Be sure that it has had sufficient time to cool before
touching it.
CAUTION: When handling the heat sink assembly, take care to avoid
sharp edges on the heat sink.
3. Verify that the chips, expansion cards, and SEC cartridge and heat sink
assembly or assemblies are fully seated in their sockets or connectors.
4. To ensure that the chips are fully seated in their sockets, press firmly on the
top of each chip.
5. Verify that all jumpers are set correctly.
6. Check all cable connectors inside the computer to verify that they are firmly
attached to their appropriate connectors.
7. Reinstall the computer cover.
8. Reconnect the computer and any attached peripherals to their power sources,
and turn them on.
