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 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 by 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
