virus
A self-starting program designed to cause inconvenience. Virus programs have
been known to corrupt the files stored on a hard drive or to replicate themselves
until a computer or network runs out of memory.
The most common way that virus programs move from one computer to another
is through “infected” diskettes, from which they copy themselves to the hard
drive. To guard against virus programs, do the following:
• Periodically run a virus-checking utility on your computer's hard drive
• Always run a virus-checking utility on any diskettes (including commercially sold
software) before using them
VLSI

VRAM
Acronym for video random-access memory. Some video adapters use VRAM chips
(or a combination of VRAM and DRAM) to improve video performance. VRAM
is dual-ported, allowing the video adapter to update the screen and receive new
image data at the same time.
VRM
Abbreviation for voltage regulator module.

Wakeup on LAN
The ability for the power in a client station to be turned on by the network. Remote
wake-up enables software upgrading and other management tasks to be performed
on users' machines after the work day is over. It also enables remote users to gain
access to machines that have been turned off. Intel calls remote wake-up
"Wake-on-LAN."
