instruction set . The set of instructions of a
computer, of a programming language, or of the
programming languages in a programming system.
interrupt . An instruction that directs the
microprocessor to suspend what it is doing and run
a specified routine. When the routine is complete,
the microprocessor resumes its original work. See
also routine.
I/O . Input/output.
ISA . Industry Standard Architecture.
ISO . International Organization for
Standardization. An organization of national
standards bodies from various countries established
to promote development of standards to facilitate
international exchange of goods and services, and
develop cooperation in intellectual, scientific,
technological, and economic activity.
J
jack . A connecting device to which a wire or wires
of a circuit can be attached and that is arranged for
insertion of a plug.
jumper . A device, such as a short wire, used to
open or close a circuit.
K
KB . Kilobyte.
kilobyte . Approximately 1000 bytes.
L
LAN . See local area network.
legacy device . A device that is not Plug and Play
(automatic configuring) compatible. A legacy device
must be manually configured by setting its switches
or jumpers, and then manually assigned computer
resources using the computer configuration/setup
utility program. Contrast with Plug and Play
device.
load . To bring all or part of a computer program
into memory from auxiliary storage so that the
computer can run the program.
local area network (LAN) . (1) A computer network
located on a user's premises within a limited
geographical area. Communication within a local
area network is not subject to external regulations;
however, communication across the LAN boundary
may be subject to some form of regulation. (2) A
network in which a set of devices are connected to
one another for communication and that can be
connected to a larger network.
logical . (1) Pertaining to content or meaning as
opposed to location or actual implementation.
(2) Pertaining to a view or description of data that
does not depend on the characteristics of the
computer system or the physical storage.
(3) Contrast with physical.
low-level format . A type of disk formatting that
erases all readable information from a hard disk by
writing zeros on all data sections of the disk to
ensure that no readable information is left on the
disk. Low-level formatting requires a low-level
format program, which is available from a number
of manufacturers.
M
MB . Megabyte.
megabyte . (1) For processor storage and real and
virtual memory, 2
20
or 1048576 bytes. (2) For disk
storage capacity, 1000 KB. (3) For transmission
rates, 1000000 bytes.
megahertz (MHz) . A unit of measure of frequency
equal to 1000000 cycles per second.
memory . Addressable storage space in the
computer that is used for temporary storage of
instructions and data while a program is running, or
for permanent storage of microcode. Contrast with
auxiliary storage.
menu . A list of choices that gives users access to
actions that can be applied to an object.
MHz . Megahertz.
