Glossary

I

icon

—A small image displayed on the screen that represents a 

function, file, or program.

interlaced

—A method of refreshing a computer screen, in 

which only every other line of pixels is refreshed. Interlaced 
monitors take two passes to create a complete screen 
image. Compare 

non-interlaced.

internal device

—See 

device.

Internet

—The decentralized, world-wide network of computers 

that provides electronic mail, the World Wide Web, and other 
services. See also 

World Wide Web.

K

keyboard shortcut

—A key or combination of keys that you 

use to perform a task instead of using a pointing device such 
as a mouse. 

L

L1 (level one) cache

—Memory cache built into the processor 

to help improve processing speed. See also 

cache, CPU 

cache, L2 cache.

L2 (level two) cache

—Memory cache installed on the 

motherboard to help improve processing speed. It is slower 
than L1 cache and faster than main memory. See also 
cache, CPU cache, L1 cache.

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.
