10BASE-T is Ethernet over UTP Category III, IV, or V
unshielded twisted-pair media.
The two-pair twisted-media implementation of 100BASET is called 100BASE-TX.
Adaptive Differential Pulse Code Modulation, a new
technology improved from PCM, which encodes analog
sounds to digital form.
AMR (Adaptive Multi-Rate) is an audio data compression
scheme optimized for speech coding, which is adopted
as the standard speech codec by 3GPP.
Applets are small Java programs that can be embedded
in an HTML page. The rule at the moment is that an
applet can only make an Internet connection to the
computer form that the applet was sent.
American Standard Code For Information Interchange, it
is the standard method for encoding characters as 8-bit
sequences of binary numbers, allowing a maximum of

Address Resolution Protocol. ARP is a protocol that
resides at the TCP/IP Internet layer that delivers data on
the same network by translating an IP address to a
physical address.
Audio Video Interleave, it is a Windows platform audio

Communication has four components: sender, receiver,
message, and medium. In networks, devices and
application tasks and processes communicate messages
to each other over media. They represent the sender and
receivers. The data they send is the message. The
cabling or transmission method they use is the medium.
In networking, two devices establish a connection to
communicate with each other.
Developed by Microsoft, DHCP (Dynamic Host
Configuration Protocol) is a protocol for assigning
dynamic IP addresses to devices on a network. With
dynamic addressing, a device can have a different IP
address every time it connects to the network. In some
systems, the device's IP address can even change while
it is still connected. It also supports a mix of static and
dynamic IP addresses. This simplifies the task for
network administrators because the software keeps track
of IP addresses rather than requiring an administrator to
manage the task. A new computer can be added to a
network without the hassle of manually assigning it a
unique IP address. DHCP allows the specification for the
service provided by a router, gateway, or other network
device that automatically assigns an IP address to any
device that requests one.
Domain Name System is an Internet service that
translates domain names into IP addresses. Since
domain names are alphabetic, they're easier to
remember. The Internet however, is really based on IP
addresses every time you use a domain name the DNS
will translate the name into the corresponding IP
address. For example, the domain name

An enterprise network consists of collections of networks
connected to each other over a geographically dispersed
area. The enterprise network serves the needs of a
widely distributed company and operates the company’s
mission-critical applications.
The most popular LAN communication technology. There
are a variety of types of Ethernet, including 10Mbps
(traditional Ethernet), 100Mbps (Fast Ethernet), and
1,000Mbps (Gigabit Ethernet). Most Ethernet networks
use Category 5 cabling to carry information, in the form
of electrical signals, between devices. Ethernet is an
implementation of CSMA/CD that operates in a bus or
star topology.
Fast Ethernet
Fast Ethernet, also called 100BASE-T, operates at 10 or
100Mbps per second over UTP, STP, or fiber-optic
Firewall is considered the first line of defense in
protecting private information. For better security, data
can be encrypted. A system designed to prevent
unauthorized access to or from a private network.
Firewalls are frequently used to prevent unauthorized
Internet users from accessing private networks
connected to the Internet, especially Intranets all
messages entering or leaving the intranet pass through
the firewall, which examines each message and blocks
those that do not meet the specified security criteria.

Short for hexadecimal refers to the base-16 number
system, which consists of 16 unique symbols: the
numbers 0 to 9 and the letters A to F. For example, the
decimal number 15 is represented as F in the
hexadecimal numbering system. The hexadecimal
system is useful because it can represent every byte (8
bits) as two consecutive hexadecimal digits. It is easier
for humans to read hexadecimal numbers than binary
This is a private network, inside an organization or
company that uses the same software you will find on the
public Internet. The only difference is that an Intranet is
used for internal usage only.
The Internet is a globally linked system of computers that
are logically connected based on the Internet Protocol
(IP). The Internet provides different ways to access
private and public information worldwide.
Internet address To participate in Internet communications and on Internet
Protocol-based networks, a node must have an Internet
address that identifies it to the other nodes. All Internet
addresses are IP addresses
Internet Protocol is the standard that describes the layout
of the basic unit of information on the Internet (the
packet) and also details the numerical addressing format
used to route the information. Your Internet service
provider controls the IP address of any device it connects
to the Internet. The IP addresses in your network must
conform to IP addressing rules. In smaller LANs, most
people will allow the DHCP function of a router or
gateway to assign the IP addresses on internal networks.
IP address
IP address is a 32-binary digit number that identifies
each sender or receiver of information that is sent in
packets across the Internet. For example is
an IP address. When you “call” that number, using any
connection methods, you get connected to the computer
that “owns” that IP address.

ISP (Internet Service Provider) is a company that
maintains a network that is linked to the Internet by way
of a dedicated communication line. An ISP offers the use
of its dedicated communication lines to companies or
individuals who can’t afford the high monthly cost for a
direct connection.
Java is a programming language that is specially
designed for writing programs that can be safely
downloaded to your computer through the Internet
without the fear of viruses. It is an object-oriented multithread programming best for creating applets and
applications for the Internet, Intranet and other complex,
distributed network.
Local Area Network a computer network that spans a
relatively small area sharing common resources. Most
LANs are confined to a single building or group of

NWay Protocol
network appear to the Internet as a single address. For
routing messages properly within your network, each
device requires a unique IP address. But the addresses
may not be valid outside your network. NAT solves the
problem. When devices within your network request
information from the Internet, the requests are forwarded
to the Internet under the router's IP address. NAT
distributes the responses to the proper IP addresses
within your network.
A network consists of a collection of two or more devices,
people, or components that communicate with each
other over physical or virtual media. The most common
types of network are:
LAN – (local area network): Computers are in close
distance to one another. They are usually in the same
office space, room, or building.
WAN – (wide area network): The computers are in
different geographic locations and are connected by
telephone lines or radio waves.
A network protocol that can automatically negotiate the
highest possible transmission speed between two
PCM (Pulse Code Modulation) is a technique for
converting analog audio signals into digital form for
Packet Internet Groper, a utility used to determine
whether a specific IP address is accessible. It functions
by sending a packet to the specified address and waits
for a reply. It is primarily used to troubleshoot Internet
Point-to-Point Protocol over Ethernet. PPPoE is a
specification for connecting the users on an Ethernet to
the Internet through a common broadband medium, such
as DSL or cable modem. All the users over the Ethernet
share a common connection.

Communication on the network is governed by sets of
rules called protocols. Protocols provide the guidelines
devices use to communicate with each other, and thus
they have different functions. Some protocols are
responsible for formatting and presenting and presenting
data that will be transferred from file server memory to
the file server’s net work adapter Others are responsible
for filtering information between networks and forwarding
data to its destination. Still other protocols dictate how
data is transferred across the medium, and how servers
respond to workstation requests and vice versa.
Common network protocols responsible for the
presentation and formatting of data for a network
operating system are the Internetwork Packet Exchange
(IPX) protocol or the Internet Protocol (IP). Protocols that
dictate the format of data for transferors the medium
include token-passing and Carrier Sense Multiple Access
with Collision Detection (CSMA/CD), implemented as
token-ring, ARCNET, FDDI, or Ethernet. The Router
Information Protocol (RIP),a part of the Transmission
Control Protocol/Internet Protocol (TCP/IP) suite,
forwards packets from one network to another using the
same network protocol.
RJ-45 connector is used for Ethernet cable connections.
A router is the network software or hardware entity
charged with routing packets between networks.
RTP (Real-time Transport Protocol) is a data transfer
protocol defined to deliver live media to the clients at the
same time, which defines the transmission of video and
audio files in real time for Internet applications.
RTSP (Real-time Streaming Protocol) is the standard
used to transmit stored media to the client(s) at the
same time, which provides client controls for random
access to the content stream.

Subnet mask
It is a simple computer that provides resources, such as
files or other information.
SIP (Session Initiated Protocol) is a standard protocol
that delivers the real-time communication for Voice over
IP (VoIP), which establishes sessions for features such
as audio and video conferencing.
The Simple Mail Transfer Protocol is used for Internet
Simple Network Management Protocol. SNMP was
designed to provide a common foundation for managing
network devices.
In LANs, a station consists of a device that can
communicate data on the network. In FDDI, a station
includes both physical nodes and addressable logical
devices. Workstations, single-attach stations, dual-attach
stations, and concentrators are FDDI stations.
In TCP/IP, the bits used to create the subnet are called
the subnet mask.
Transmission Control Protocol/Internet Protocol is a
widely used transport protocol that connects diverse
computers of various transmission methods. It was
developed y the Department of Defense to connect
different computer types and led to the development of
the Internet.
A transceiver joins two network segments together.
Transceivers can also be used to join a segment that
uses one medium to a segment that uses a different
medium. On a 10BASE-5 network, the transceiver
connects the network adapter or other network device to
the medium. Transceivers also can be used on 10BASE2 or 10BASE-T networks to attach devices with AUI

User Name
The User Datagram Protocol is a connectionless protocol
that resides above IP in the TCP/IP suite
The USERNAME is the unique name assigned to each
person who has access to the LAN.
It is a program that performs a specific task.
Unshielded twisted-pair. UTP is a form of cable used by
all access methods. It consists of several pairs of wires
enclosed in an unshielded sheath.
Wide-Area Network. A wide-area network consists of
groups of interconnected computers that are separated
by a wide distance and communicate with each other via
common carrier telecommunication techniques.
WEP is widely used as the basic security protocol in WiFi networks, which secures data transmissions using 64bit or 128-bit encryption.
Windows is a graphical user interface for workstations
that use DOS.
WPA (Wi-Fi Protected Access ) is used to improve the
security of Wi-Fi networks, replacing the current WEP
standard. It uses its own encryption, Temporal Key
Integrity Protocol (TKIP), to secure data during
Wi-Fi Protected Access 2, the latest security specification
that provides greater data protection and network access
control for Wi-Fi networks. WPA2 uses the governmentgrade AES encryption algorithm and IEEE 802.1X-based
authentication, which are required to secure large
corporate networks.
