memory

Electronic storage area in a computer that retains information and programs. A computer has two types of memory — read-only memory (ROM) and random access memory (RAM).

menu

A video display of programs or options.

microprocessor

A semiconductor central processing unit that is the principal component of a microcomputer. Usually contained on a single chip that includes an arithmetic logic unit, control logic, and control-memory unit.

MIDI

Musical Instrument Digital Interface. A standard serial bus, digital interface designed to connect electronic musical devices. MIDI has no innate sound of its own.

mini-PCI

A communications standard that offers smaller size, greater design flexibility, and reduced cost for mobile platforms.

MIR

Medium Infrared, an infrared technology that sends data at 1.152 Mbit/second (1,152,000 bits per second).

MMX

A set of 57 multimedia instructions built into Intel’s Pentium microprocessors. MMX- enabled microprocessors handle many common multimedia operations, such as digital signal processing (DSP), that are normally handled by a separate sound or video card.

However, only software especially written to call MMX instructions — MMX-enabled software — can take advantage of the MMX instruction set.

mode

A method of operation; for example, the NEC Versa operates in either normal or power-saving modes.

modem

MOdulator-DEModulator. A device that links computers over a telephone line.
