Abbreviation for ISA Configuration Utility.
I/O
Abbreviation for input/output. The keyboard is an input device,
and a printer is an output device. In general, I/O activity can be
differentiated from computational activity. For example, when a
program sends a document to the printer, it is engaging in
output activity; when the program sorts a list of terms, it is
engaging in computational activity.
ID
Abbreviation for identification.
interlacing
A technique for increasing video resolution by only updating
alternate horizontal lines on the screen. Because interlacing
can result in noticeable screen flicker, most users prefer
noninterlaced video adapter resolutions.
internal processor cache
An instruction and data cache built in to the processor. The
Intel Pentium processor includes a 16-KB internal cache,
which is set up as an 8-KB read-only instruction cache and an
8-KB read/write data cache.
IPX
Acronym for internetwork packet exchange.
IRQ
Abbreviation for interrupt request. A signal that data is about to
be sent to or received by a peripheral device travels by an IRQ
line to the processor. Each peripheral connection must be
assigned an IRQ number. For example, the first serial port in
your computer (COM1) is assigned to IRQ4 by default. Two
devices can share the same IRQ assignment, but you cannot
operate both devices simultaneously.
ISA
Acronym for Industry-Standard Architecture. A 16-bit
expansion bus design. The expansion-card connectors in an
ISA computer are also compatible with 8-bit ISA expansion
cards.
ITE
Abbreviation for information technology equipment.
A method for increasing addressable RAM by using the hard-
disk drive. For example, in a computer with 16 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
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-disk drive or to replicate themselves until a computer or
network runs out of memory.
The most common way that virus programs move from one
computer 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
VLSI
Abbreviation for very-large-scale integration.
Vpp
Abbreviation for peak-point voltage.
VRAM
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.
W
Abbreviation for watt(s).
WH
Abbreviation for watt-hour(s).
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-disk drive.
Running the Control Panel or Windows Setup program may
change options in the win.ini file. On other occasions, you
