Video resolution-640 x 480, 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. An abbreviation for VESA local bus. A standard for local bus implementation developed by the Video Electronics Standards Association. Abbreviation for very-large-scale integration. An operating mode supported by Intel386 or higher microprocessors, virtual 8086 mode allows operating environments- such as Windows-to run multiple programs in separate 1-MB sections of memory. Each 1-MB section is called a virtual machine. 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. A self-starting program designed to inconvenience 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 programs 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 utility on your computer's hard-disk drive. Always run a virus-checking utility on any diskettes (including commercially sold software) before using them. Abbreviation for peak-point voltage. Abbreviation 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. Abbreviation for watt(s). 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-disk drive. Revising the Control Panel settings or running the Windows Setup program may change options in the win.ini file.

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 set-
tings for Windows application programs that
are installed on the hard-disk drive.
Revising the Control Panel settings or run-
ning the 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.
