Glossary 143
virtual memory
A method for increasing addressable RAM by using the
hard drive. For example, in a system 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 system or network runs out of memory. The
most common way that virus programs move from one
system 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
system'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

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 fro voltage regulator module.
W

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."

viewing by Web browsers using the HTTP protocol.

Winbind

to log in using workstations that have either UNIX or
Windows NT operating systems. The program makes
workstations using UNIX functional in NT domains,
by making NT look like UNIX to each UNIX workstation.
win.ini file
A start-up file for the Windows operating system.
When you start Windows, it consults the
win.ini file
to determine a variety of options for the Windows
operating environment. Among other things, the
win.ini file records what printer(s) and fonts are
installed for Windows. The
win.ini file also usually
includes sections that contain optional settings for
Windows application programs that are installed on
the hard drive. Running the Control Panel or Windows
Setup program may change options in the
win.ini file.
On other occasions, you may need to change or add
options to the
win.ini file manually with a text editor
such as Notepad.
Windows 95
An integrated and complete Microsoft Windows
operating system that does not require MS-DOS and
