Host

A computer that serves other terminals in a network, providing

services such as network control, database access, special

programs, supervisory programs, or programming languages.

Liquid Crystal Display (LCD)

A display that uses liquid crystal sealed between two glass plates.

The crystals are excited by precise electrical charges, causing

them to reflect light outside according to their bias. They use little

electricity and react relatively quickly. They require external light to

reflect their information to the user.

Light Emitting Diode (LED)

A low power electronic light source commonly used as an indicator

light. It uses less power than an incandescent light bulb but more

than a Liquid Crystal Display (LCD).

RAM

Random Access Memory. Data in RAM can be accessed in random

order, and quickly written and read. This memory is volatile and

therefore data is lost when power is not present.

RTC

Real Time Clock.

Terminal

A Datalogic portable computer product.
