.

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.
