LAN (Local Area Network)—A group of computers or other devices 
dispersed over a relatively limited area and connected by a 
communications link that enables any device to interact with any 
other on the network.
LED (Light Emitting Diode)—A solid state lamp (SSL) that uses 
light-emitting diodes (LEDs) as the source of light, which offers 
long life and high efficiency output. Multiple diodes are used 
together, since the light created by individual light-emitting diodes is 
small compared to incandescent and compact fluorescent lamps.
LCD (Liquid Crystal Display)—A type of display that uses a liquid 
substance between two transparent electrode panels. When an 
electric current passes through the electrodes, the molecules in the 
liquid form a crystalline pattern that polarizes the light passing 
through it. A filter over the electrodes permits only non-polarized 
light to pass to the surface of the display, creating light and dark 
pixels.
load—To move information from a storage device (such as a hard disk) 
into memory for processing.
local area network—See LAN.
logical drive—A section of a disk that is recognized by the operating 
system as a separate disk drive. A system’s logical drives may differ 
from its physical drives. For example, a single hard disk drive may 
be partitioned into two or more logical drives.
M
memory—Typically refers to the computer’s main memory, where 
applications are run and data is temporarily stored and processed. 
Memory can be volatile and hold data temporarily, such as RAM, or 
it can be nonvolatile and hold data permanently, such as ROM. A 
computer’s main memory is RAM. See also RAMROM.
microprocessor—See Central Processing Unit (CPU).
MIDI (Musical Instrument Digital Interface)—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.
motherboard—The computer’s main circuit board that contains the 
processor, memory, and other primary components.
MS-DOS prompt—See system prompt.
