video memory Most VGA and SVGA video adapters include memory chips in addition to your computer's RAM. The amount of video memory installed primarily influences the number of colors that a program can display (with the appropriate video drivers and monitor capabilities). video mode Video adapters normally support multiple text and graphics display modes. Character-based software displays in text modes that can be defined as x columns by y rows of characters. Graphics-based software displays in graphics modes that can be defined as x horizontal by y vertical pixels by z colors. video resolution Video resolution-800 x 600, for example-is expressed as the number of pixels across by the number of pixels up and down. To display a program at a specific graphics resolution, you must install the appropriate video drivers and your monitor must support the resolution. virtual memory A method for increasing addressable RAM by using the hard drive. For example, in a computer with 16 MB of RAM and 16 MB of virtual memory set up on the hard drive, the operating system would manage the system as though it had 32 MB of physical RAM. virus A self-starting program designed to inconvenience you. 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 via "infected" diskettes, from which they copy themselves to the hard drive. To guard against virus programs, you should 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 Abbreviation for very-large-scale integration. VLVESA Acronym for very low voltage enterprise system architecture. vpp Abbreviation for peak-point voltage. 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. W Abbreviation for watt(s). 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." WH Abbreviation for watt-hour(s). Winbind A program that allows users in a heterogeneous network to log in using workstations that have UNIX operating systems. The program makes workstations using UNIX functional in Windows domains, by making Windows appear like UNIX to each UNIX workstation. 212 Glossary

video memory
Most VGA and SVGA video adapters include memory
chips in addition to your computer's RAM. The amount
of video memory installed primarily influences the
number of colors that a program can display (with the
appropriate video drivers and monitor capabilities).
video mode
Video adapters normally support multiple text and
graphics display modes. Character-based software
displays in text modes that can be defined as
x
columns
by
y
rows of characters. Graphics-based software
displays in graphics modes that can be defined as
x
horizontal by
y
vertical pixels by
z
colors.
video resolution
Video resolution—800 x 600, for example—is
expressed as the number of pixels across by the number
of pixels up and down. To display a program at a specific
graphics resolution, you must install the appropriate
video drivers and your monitor must support the
resolution.
virtual memory
A method for increasing addressable RAM by using the
hard drive. For example, in a computer with 16 MB of
RAM and 16 MB of virtual memory set up on the hard
drive, the operating system would manage the system
as though it had 32 MB of physical RAM.
virus
A self-starting program designed to inconvenience you.
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 via “infected” diskettes,
from which they copy themselves to the hard drive.
To guard against virus programs, you should 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
