Universal Serial Bus (USB)
An all-purpose input/output connector that lets you attach a digital camera, audio player, memory key, mouse, external drive, or printer.

Short for wireless fidelity, an umbrella term for wireless Ethernet.

802.11g, capable of 54 Mbps, is succeeding (and in-corporates) 802.11b.
Some corporations prefer 802.11a, also 54 Mbps. It is possible for a wireless card to integrate both g (with b) and a.
Virtually every notebook incorporates wired Ethernet; many include wireless, too.
XGA (Extended Graphics Array)
One of the two most common screen resolutions for notebooks and desktops:1,024 pixels horizontally by 768 vertically.
Equally common is SXGA+ (1,400 by 1,050).
Other resolutions are SXGA (1,280 by 1,024, used more on desktops than notebooks), and
UXGA (1,600 by 1,200).
The higher resolutions make for crisp graphics and small text.
Widescreen displays typically use WXGA (1280 by 768), WSXGA+ (1680 by 1050), and WUXGA (1920 by 1200).
