M<br />
liquid crystal display (LCD) — A type of display that uses a liquid<br />
substance between two transparent electrode panels. When an<br />
electric current passes through the electrodes, the molecules in the<br />
liquid form a crystalline pattern that polarizes the light passing<br />
through it. A filter over the electrodes permits only non-polarized<br />
light to pass to the surface of the display, creating light and dark<br />
pixels.<br />
load — To move information from a storage device (such as a hard disk)<br />
into memory for processing.<br />
local area network — See LAN.<br />
logical drive — A section of a disk that is recognized by the operating<br />
system as a separate disk drive. A system’s logical drives may differ<br />
from its physical drives. For example, a single hard disk drive may<br />
be partitioned into two or more logical drives.<br />
memory — Typically refers to the computer’s main memory, where<br />
programs are run and data is temporarily stored and processed.<br />
Memory can be volatile and hold data temporarily, such as RAM, or<br />
it can be nonvolatile and hold data permanently, such as ROM. A<br />
computer’s main memory is RAM. See RAM, ROM.<br />
microprocessor — See central processing unit (CPU).<br />
MIDI (Musical Instrument Digital Interface) — A standard for<br />
connecting musical instruments, synthesizers, and computers. The<br />
MIDI standard provides a way of translating music into a form<br />
computers can use, and vice versa.<br />
modem — Short for “modulator/demodulator.” A device that converts<br />
information from digital to analog, and back to digital, enabling<br />
information to pass back and forth between digital computers and<br />
analog telephone lines.<br />
motherboard — The computer’s main circuit board that contains the<br />
processor, memory, and other primary components.<br />
MS-DOS prompt — See system prompt.<br />
multi-function drive — A DVD drive that can read and write to CD and<br />
DVD media.<br />
multimedia — A combination of two or more media, such as sound,<br />
animation, and video in a computer program or presentation.<br />
Musical Instrument Digital Interface — See MIDI.
