router, or access point, the perspective is reversed, and the hub receives on pins 1 and 2. This wiring is

referred to as Media Dependant Interface - Crossover (MDI-X). See also AES.

NAT

A technique by which several hosts share a single IP address for access to the Internet.

Network Address Translation

NAT. A technique by which several hosts share a single IP address for access to the Internet.

NIC

Network Interface Card. An adapter in a computer which provides connectivity to a network.

packet

A block of information sent over a network. A packet typically contains a source and destination network

address, some protocol and length information, a block of data, and a checksum.

RFC

Request For Comment. Refers to documents published by the Internet Engineering Task Force (IETF)

proposing standard protocols and procedures for the Internet. RFCs can be found at www.ietf.org.

router

A device that forwards data between networks. An IP router forwards data based on IP source and

destination addresses.

SSID

A Service Set Identification is a thirty-two character (maximum) alphanumeric key identifying a wireless

local area network. For the wireless devices in a network to communicate with each other, all devices must

be configured with the same SSID.

This is typically the configuration parameter for a wireless PC card. It corresponds to the ESSID in the

wireless Access Point and to the wireless network name. See also Wireless Network Name and ESSID.

Subnet Mask

A mask used to determine what subnet an IP address belongs to. Subnetting enables a network administrator

to further divide an IP address into two or more subnets.

An IP address has two components, the network address and the host address. For example, consider the IP

address 150.215.017.009. Assuming this is part of a Class B network, the first two numbers (150.215)

represent the Class B network address, and the second two numbers (017.009) identify a particular host on

this network.

Subnetting enables the network administrator to further divide the host part of the address into two or more

subnets. In this case, a part of the host address is reserved to identify the particular subnet. This is easier to

see if we show the IP address in binary format. The full address is: 10010110.11010111.00010001.00001001

The Class B network part is: 10010110.11010111

and the host address is 00010001.00001001
