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 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

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.

J

JAVA

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

multi-thread programming best for creating applets

and applications for the Internet, Intranet and other

complex, distributed network.

L

LAN

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.

M

MJPEG

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

MPEG4 is designed to enable transmission and

reception of high-quality audio and video over the

Internet and next-generation mobile telephones.

N

NAT

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.

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.

NWay Protocol

A network protocol that can automatically negotiate

the highest possible transmission speed between two

devices.

P

PCM

PCM (Pulse Code Modulation) is a technique for

converting analog audio signals into digital form for

transmission.

PING

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.

PPPoE

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.

Protocol

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.

R

RJ-45

RJ-45 connector is used for Ethernet cable

connections.

Router

A router is the network software or hardware entity

charged with routing packets between networks.

RTP

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

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.

S

Server

It is a simple computer that provides resources, such

as files or other information.

SIP

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.

SMTP

The Simple Mail Transfer Protocol is used for Internet

mail.

SNMP

Simple Network Management Protocol. SNMP was

designed to provide a common foundation for

managing network devices.

Station

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.

Subnet mask

In TCP/IP, the bits used to create the subnet are

called the subnet mask.

T

(TCP/IP)

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.

Transceiver

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.

U

UDP

The User Datagram Protocol is a connectionless

protocol that resides above IP in the TCP/IP suite

User Name

The USERNAME is the unique name assigned to

each person who has access to the LAN.

Utility

It is a program that performs a specific task.

UTP

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.

W

WAN

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

WEP is widely used as the basic security protocol in

Wi-Fi networks, which secures data transmissions

using 64-bit or 128-bit encryption.
