Subnet Mask

A subnet mask is a set of four numbers configured like an IP address. It is used to

create IP address numbers used only within a particular network.

TCP (Transmission Control Protocol)

The standard transport level protocol that provides the full duplex, stream service

on which many application protocols depend. TCP allows a process or one

machine to send a stream of data to a process on another. Software implementing

TCP usually resides in the operating system and uses the IP to transmit information

across the network.

WAN (Wide Area Network)

A system of LANs, connected together. A network that connects computers located

in separate areas, (i.e., different buildings, cities, countries). The Internet is a wide

area network.

WECA (Wireless Ethernet Compatibility Alliance)

An industry group that certifies cross-vender interoperability and compatibility

of IEEE 802.11b wireless networking products and to promote that standard for

enterprise, small business, and home environments.

WPA (Wi-Fi Protected Access)

Wi-Fi Protected Access (WPA) is an improved security system for 802.11. It is part

of the 802.11i draft security standard. WPA encompasses TKIP (Temporal Key

Integrity Protocol) along with MIC (Message Integrity Check) and other fixes to

WEP such as Weak IV (Initialization Vector) filtering and Random IV generation.

TKIP uses 802.1x to deploy and change temporary keys as opposed to static

WEP keys once used in the past. It is a significant improvement over WEP. WPA

is part of a complete security solution. WPA also requires authentication servers in

enterprise security solutions.

Requirements

(1) A WPA compatible access point or Wireless router, (2) Operating system

updates that support WPA. In Windows

®

XP, an updated Windows Zero

Configuration service is needed. Users can download the Windows

Please note that this patch requires the installation Windows XP Service Pack 1,

which is available here: http://www.microsoft.com/WindowsXP/pro/downloads/

For earlier Windows Operating systems, a WPA capable supplicant is required

such as Funk Software’s Odyssey Client.

WLAN (Wireless Local Area Network)

This is a group of computers and other devices connected wirelessly in a small

area. A wireless network is referred to as LAN or WLAN.
