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).
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. An interface for connecting suitably equipped musical
instruments to suitably equipped computers.
MIF
Management Information File. A file stored on a PC that holds system data such as a model
ID and serial number that can be manipulated over a network from a centralized location.
MMX
A processor architecture that enhances multimedia and communications. This technology
processes multiple data elements in parallel, speeding up such things as image processing,
motion video, speech synthesis, telephony, and 3-D graphics.
modem
MOdulator-DEModulator. A device that links computers over a telephone line.
MPC
Multimedia Personal Computer, a software and hardware standard developed by a
consortium of computer firms led by Microsoft. There are three MPC standards, called
MPC, MPC2, and MPC3, respectively. Each specifies a minimum hardware configuration
for running multimedia software.
MPEG
Motion Pictures Expert Group. Audio/Video technology that allows for better than VHS
quality video and almost CD quality audio by using advanced compression techniques.
MPEG files allow for more realistic motion with a smaller file size than earlier formats,
making it a popular format for digital full-length movies. Files in the MPEG format have an
.MPG extension.
N
nonvolatile memory
Storage media that retains its data when system power is turned off. Nonvolatile memory is
a complementary metal oxide semiconductor (CMOS) chip that is backed up by an internal
battery. The backup battery preserves the clock/calendar data and system configuration
parameters stored in CMOS. See volatile memory.
O
operating system
Set of programs that manage the overall operation of the computer.
overwrite
Storing information at a location where information is already stored, thus destroying the
original information.
