wireless network devices are made a part of the network through the use of an

Access Point. The Access Point connects the device to the rest of the network.

Internet

A global network connecting millions computers. As of 1998, the Internet has

more than 100 million users worldwide, and that number is still growing rapidly.

More than 100 countries are linked to the exchanges of data, news and opinions.

Internet Protocol is meant by sending data from one computer (host) to another

on the Internet. Each of the host has at least one IP Address, which identifies its

IP from other computers on the Internet. When sending or receiving messages,

the messages are divided into different packets that contain addresses of the

senders and the receivers.

IP Address

An identifier for a computer or device on a TCP/IP network. Networks using the

TCP/IP protocol route messages base on the IP address of the destination. The

format of an IP address is a 32-bit numeric address written as four numbers

separated by periods. Each ranges from 0 to 255. For example, 157.124.10.1

could be a valid IP address.

IPSec (Internet Protocol Security)

A developing standard for security at the network or packet processing layer of

network communication. IPSec will be especially useful for implementing a Virtual

Private Network or for remote user access to private networks through a dial-up

connection. The main advantage of IPSec is that security arrangements can be

handled without requiring changes to individual user computers.

ISP

Short for Internet Service Provider, or a company that provides access to the

Internet. Paid on a monthly basis, the service provider gives you a software

pack-age, username, password and access phone number. Equipped with a

modem, you can then log onto the Internet and browse the World Wide Web and

USENET, as well as to send and receive e-mails.

Local Area Network (LAN)

A computer network that spans a relatively small area. Most LANs are confined to

a single building or a group of buildings. However, one LAN can be connected to

other LANs over any distance via telephone lines and radio waves. A system of

LANs connected this way is called a wide-area network (WAN)

MAC Address (Media Access Control Address)

MAC Addresses- (Media Access Control) On a network, it is a unique 48-bit

number used in Ethernet data packets to uniquely identify an Ethernet device,

such as an Ethernet adapter.

NAT

This is an abbreviation for Network Address Translation, or translation of one IP

address in a network (inside) to a different IP address in another network

(outside). It is included in a router and the firewall of a company
