EEPROM
Electrically Erasable Programmable Read-Only Memory. An on-board non-volatile
memory chip.
Flash Disk
Non-volatile memory for storing application and configuration files.
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.
IrDA (Infrared Data Association)
An industry-sponsored organization set up in 1993 to create international standards
for the hardware and software used in infrared communication links. In this special
form of radio transmission, a focused ray of light in the infrared frequency spectrum,
measured in terahertz, or trillions of hertz (cycles per second), is modulated with
information and sent from a transmitter to a receiver over a relatively short distance.
Infrared radiation (IR) is the same technology used to control a TV set with a remote
control.
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.
