DRAM. Dynamic random access memory.
DSTN. Dual-scan, super-twisted nematic.
EDO. Enhanced Data Output or Extended Data Out. A type of
DRAM that offers faster access to data in memory.
EGA. Enhanced graphics adapter.
EIA. Electronics Industries Association.
EIA-232D. An EIA interface standard that defines the physical,
electronic, and functional characteristics of an interface line
that connects a communication device and associated
workstation. It uses a 25-pin connector and an unbalanced line
voltage.
EMS. Expanded memory specification.
fax. Facsimile machine or transmitted document.
FDD. Floppy disk drive.
fixed disk. In personal computing, fixed disk is synonymous
with hard disk.
flash memory. A rewritable storage that is used to contain
BIOS instructions and POST routines.
folder. A file used to store and organize documents.
fuel gauge. An indicator on the screen that constantly shows
the current power status of the battery pack.
HDD. Hard disk drive.
HHR. Half-horizontal resolution.
hibernation mode. One of the power-saving methods that
stores data and applications running in the computer’s memory
on the hard disk. During hibernation, the computer is
automatically turned off to save power. When power is turned
on again, the computer immediately restores the same data and
applications as when hibernation mode started, without
restarting the operating system.
high-performance mode. A method of increasing the access
time of video memories for DSTN LCDs, to produce high-
quality video on an external monitor (CRT).
high-resolution mode. Video resolutions that are greater
than 640 x 480 pels.
icon. A graphic symbol, displayed on a screen, that a user can
point to with a pointing device such as a mouse to select a
particular function or software application.
IRQ. Interrupt request.
ISA. Industry standard architecture.
ISO. International Organization for Standardization.
JEIDA. Japan Electronics Industry Development Association.
kilobyte (KB). 1024 (210) bytes.
LAN. Local area network.
LCD. Liquid crystal display.
LPT1 or LPT2. The name you can assign a parallel port to
specify its address. See also parallel port.
mAh. Milliampere hours.
megabyte (MB). 1024 kilobytes. About 1 million bytes.
memory. Often referred to as random-access memory (RAM),
measured in kilobytes (KB) or megabytes (MB) of information.
MHz. Megahertz.
microcode. One or more microinstructions used in a product
as an alternative to hard-wired circuitry to implement functions
of a processor or other system component.
MIDI. Musical Instrument Digital Interface.
modem. A device that connects your computer to a telephone
line, allowing it to communicate with another computer at
another location.
parallel port. A port used to attach such devices as dot-matrix
printers and input/output units; it transmits data 1 byte at a
time.
parity check. A redundancy check by which a recalculated
parity bit is compared with the pregiven parity bit.
password. A series of letters or numbers that you designated
to restrict access to your computer.
PC Card. A card that is based on the PCMCIA standard.
