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

9/￿%XVŒ

An abbreviation for VESA® local bus. A standard for local bus implementation de- veloped by the Video Electronics Standards Association.

9/6,

Abbreviation for very–large-scale integration.

9SS

Abbreviation for peak-point voltage.

95$0

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, thewin.ini file records what printer(s) and fonts are installed for Windows. The win.ini file also usually includes sections that contain optional set- tingsforWindows applicationprograms that are installed on the hard-disk 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 thewin.ini file manually with a text editor, such as Notepad.

Read-only files are said to be write- protected. You can write-protect a 3.5-inch diskette by sliding its write-protect tab to the open position and a 5.25-inch diskette by placing an adhesive label over its write- protect notch.

;00

Abbreviation for extended memory man- ager, a utility that allows application programs and operating environments to use extended memory in accordance with the XMS. See alsoconventionalmemory, EMM, expanded memory, extended memory, and memory manager.

;06

Abbreviation for eXtended Memory Spec- ification. See also EMS, extended memory, and memory manager.

=,)

Acronym for zero insertion force. Some computers use ZIF sockets and connec- tors to allow devices such as the microprocessor chip to be installed or removed with no stress applied to

the device.
