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.
