The global address of documents and other resources on the World Wide Web.
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.
