USB

Universal Serial Bus

USB is a serial protocol and physical link, which transmits all data differentially on a single

pair of wires. Another pair provides power to downstream peripherals.

Virtual server

A virtual server allows you to direct incoming traffic from the Internet (identified by

protocol and external port) to an internal server with a private IP address on the LAN.

WAN

Wide Area Network

WAN usually refers to a network which covers a large geographical area, and uses

communications circuits to connect the intermediate nodes. A major factor impacting

WAN design and performance is a requirement that they lease communications circuits

from telephone companies or other communications carriers.

Wi-Fi

Wireless Fidelity

A wireless data networking protocol generally used to connect PCs to a network. Also

known as 802.11b and WLAN (Wireless LAN), it is the most common means of wireless

networking and operates at 2.4 GHz.

WPA-PSK

Wi-Fi Protected Access-Pre Shared Key

WPA is an industry standard based on a subset of an early draft of 802.11i. WPA replaces

WEP's keying mechanism with a more robust system, called Temporal Key Integrity

Protocol (although TKIP is still based on RC4 encryption). (See full description of TKIP).

WPA adds a strong message integrity check and allows for authentication using 802.1X.

WEP

Wired Equivalent Privacy

Part of the IEEE 802.11 standard (ratified in September 1999), and is a scheme used to

secure wireless networks (Wi-Fi). Because a wireless network broadcasts messages using

radio, it is particularly susceptible to eavesdropping; WEP was designed to provide

comparable confidentiality to a traditional wired network, hence the name.
