Liquid Crystal Display (LCD):
Liquid crystal sealed between two sheets of
glass coated with transparent conducting material. The viewing-side
coating is etched into character forming segments with leads that
extend to the edge of the glass. Applying a voltage between the
glass sheets alters the brightness of the liquid crystal.
LSI:
Large Scale Integration.
1) A technology that allows the inclusion of up to 100,000 simple
logic gates on a single chip.
2) An integrated circuit that uses large scale integration.
M
main board:
See
motherboard.
megabyte (MB):
A unit of data storage equal to 1024 kilobytes.
See also
kilobyte.
megahertz:
A unit of wave frequency that equals 1 million cycles per
second.
See also
hertz.
menu:
A software interface that displays a list of options on the screen.
Also called a screen.
microprocessor:
A hardware component contained in a single integrated
circuit that carries out instructions. Also called the central
processing unit (CPU), one of the main parts of the computer.
mode:
A method of operation, for example, the Boot Mode, Sleep Mode or
the Hibernation Mode.
modem:
Derived from modulator/demodulator, a device that converts
(modulates) digital data for transmission over telephone lines and
then converts modulated data (demodulates) to digital format where
received.
monitor:
A device that uses rows and columns of pixels to display
alphanumeric characters or graphic images.
See also
CRT.
motherboard:
A name sometimes used to refer to the main printed circuit
board in processing equipment. It usually contains integrated
circuits that perform the processor’s basic functions and provides
connectors for adding other boards that perform special functions.
Sometimes called a main board.
N
non-system disk:
A formatted floppy diskette you can use to store
programs and data but you cannot use to start the computer.
See
system disk.
nonvolatile memory:
Memory, usually read-only (ROM), that is capable of
permanently storing information. Turning the computer’s power off
does not alter data stored in nonvolatile memory.
numeric keypad overlay:
A feature that allows you to use certain keys on
the keyboard to perform numeric entry, or to control cursor and page
movement.
