YLUWXDOPHPRU\
A method for increasing addressable
RAM by using the hard-disk drive.
(MS-DOS does not support true virtual
memory, which must be implemented at
the operating system level.) For example,
in a computer with 8 MB of RAM and
16 MB of virtual memory set up on the
hard-disk drive, the operating system
would manage the system as though it
had 24 MB of physical RAM.
YLUXV
A self-starting program designed to incon-
venience you. Virus programs have been
known to corrupt the files stored on a
hard-disk drive or to replicate themselves
until a system or network runs out of
memory.
The most common way that virus pro-
grams move from one system to another
is via infected diskettes, from which
they copy themselves to the hard-disk
drive. To guard against virus programs,
you should do the following:
Periodically run a virus-checking util-
ity on your computers hard-disk
drive
Always run a virus-checking utility on
any diskettes (including commer-
cially sold software) before using
them

When you start Windows, it consults the
win.ini file to determine a variety of options
for the Windows operating environment.

includes sections that contain optional set-
tings for Windows application programs that
are installed on the hard-disk drive.
