The two-pair twisted-media implementation of 100BASE-T 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 256 characters.
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 and video
file type, a common format for small movies and videos.
Bootstrap Protocol is an Internet protocol that can automatically
configure a network device in a diskless workstation to give its
own IP address.
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
www.network_camera.com might translate to 192.167.222.8.
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, also called 100BASE-T, operates at 10 or
100Mbps per second over UTP, STP, or fiber-optic media.
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.
A gateway links computers that use different data formats
together.
Groups consist of several user machines that have similar
characteristics such as being in the same department.
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 numbers.

logically connected based on the Internet Protocol (IP). The
Internet provides different ways to access private and public
information worldwide.
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 is a 32-binary digit number that identifies each sender
or receiver of information that is sent in packets across the
Internet. For example 80.80.80.69 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 objectoriented multi-thread 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 buildings.
MJPEG (Motion JPEG) composes a moving image by storing
each frame of a moving picture sequence in JPEG compression,
and then decompressing and displaying each frame at rapid
speed to show the moving picture.
MPEG4 is designed to enable transmission and reception of highquality audio and video over the Internet and next-generation
mobile telephones.

Network Address Translator generally applied by a router that
makes many different IP addresses on an internal 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 devices.
PCM (Pulse Code Modulation) is a technique for converting
analog audio signals into digital form for transmission.
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 connections.
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.

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.
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 mail.
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
10BASE-2 or 10BASE-T networks to attach devices with AUI
ports.
The User Datagram Protocol is a connectionless protocol that
resides above IP in the TCP/IP suite

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 Wi-Fi
networks, which secures data transmissions using 64-bit or 128bit 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 transmission.
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 government-grade AES
encryption algorithm and IEEE 802.1X-based authentication,
which are required to secure large corporate networks.
