Glossary
MPEG (Motion Picture Experts Group): Proposed universal standard for
the conversion of analog video images to a digital format. MPEG is
a working committee under the auspices of the International
Standards Organization (ISO) that is attempting to define standards
for digital compression/decompression of motion video/audio for
use in computer systems. Its first priority is to develop methods for
encoding video within the 1.5 Mbit/second CD-ROM data rate. As
an evolving standard, MPEG-2 extends MPEG compression and
decompression capabilities.
multimedia: A combination of two or more elements, such as sound,
animation, and video in a computer program or presentation.
Multimedia programs, which require huge amounts of storage
space, have become very popular with the wide availability of CD-
ROM drives.
multiprocessing: The simultaneous execution of different programs or of
different parts of the same program by two or more CPUs installed
in the same computer.
multitasking: A technique in which the computer runs one program for a
short time and then switches to the next program. Because people's
sense of time is much slower than the computer's speed, the
programs seem to run simultaneously.
Musical Instrument Digital Interface (MIDI): A standard for connecting
musical instruments, synthesizers, and computers. The MIDI
standard provides a way of translating music into a form computers
can use, and vice versa.
N
network: A collection of interconnected, individually controlled
computers, together with the hardware and software used to connect
them. A network allows users to share data and peripheral devices
such as printers, and to exchange electronic mail.
Network Interface Controller (NIC): A controller that acts as the
communications interface between a personal computer and a
network.
Netware Loadable Module (NLM): A program you load and unload
while the server is running. Four types of NLMs exist: management
utilities and server application modules, disk drivers, LAN drivers,
and name space NLMs.
