Ethernet

The most popular LAN communication technology.

There are a variety of types of Ethernet, including 10

Mbps (traditional Ethernet), 100 Mbps (Fast Ethernet),

and 1,000 Mbps (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.

F

Fast Ethernet

Fast Ethernet, also called 100BASE-T, operates at 10

or 100Mbps per second over UTP, STP, or fiber-optic

media.

Firewall

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.

G

Gateway

A gateway links computers that use different data

formats together.

Group

Groups consist of several user machines that have

similar characteristics such as being in the same

department.

H

HEX

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.

I

IEEE

Institute of Electrical and Electronic Engineers.

Intranet

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.

Internet

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

IP

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 80.80.80.69 is

an IP address, it is the closet thing the Internet has to

telephone numbers. 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.

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.

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

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
