Glossary
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, standby mode
or the hibernation mode.
modem:
Derived from modulator/demodulator, a device that converts
(modulates) digital data for transmission over telephone lines and

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.
