Infrastructure Mode:

an 802.11 networking framework where devices communicate with eachother by first going

through an Access Point (AP). In this mode, wireless devices can communicate with each other or with a wired net-
work.

IP Address:

The address of a computer attached to a TCP/IP network. Every client and server station must have a

unique IP address. It can be provided by the user, network administrator, or obtained automatically.

LAN:

Local Area Network. A computer network that exists over a small area. LANs are generally found in a single

building or group of buildings. LANs can be connected to other LANs over any distance by telephone lines and radio
waves. A system of LANs connected in this way is called a wide-area network (WAN).

MAC address:

(also called an Ethernet address) is a number which uniquely identifies a computer that has an Ethernet

interface.

Open Key:

A means of client authentication between the wireless NIC and the AP. Open key authentication involves

supplying the correct Service Set Identifier (SSID).

Shared Key:

A means of client authentication between the wireless network interface card (NIC) and the AP. With

shared key authentication, the AP sends the client device a text packet that the client must then encrypt with the cor-
rect WEP key and return to the AP.

USB wireless adapter:

a wireless device that attaches to a PC computer through a USB port.

WEP:

Short for Wired Equivalent Privacy, a security protocol for WLANs. WEP is designed to provide the same level

of security as that of a wired LAN by encrypting data so it is protected as it is transmitted.

Wi-Fi:

Short for wireless fidelity. The term is commonly used when referring to any type of 802.11 network.

Wireless Adapter:

a wireless PCMCIA card, integrated adapter, or USB wireless adapter that inserts into a PC laptop

computer.

WLAN:

A wireless LAN that transmits over the air, typically in an unlicensed frequency such as the 2.4GHz band.
