Host
A computer that serves other mobile computers in a network, providing services such
as network control, database access, special programs, supervisory programs, or
programming languages.
WLAN
A Wireless Local Area Network links devices via a wireless distribution method
(typically spread-spectrum or OFDM radio), and usually provides a connection
through an access point to the wider internet. This gives users the mobility to move
around within a local coverage area and still be connected to the network.
IEEE 802.11
A set of standards carrying out wireless local area network (WLAN) computer
communication in the 2.4, 3.6 and 5 GHz frequency bands. They are created and
maintained by the IEEE LAN/MAN Standards Committee.
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).
Null modem cable
RS-232 serial cable where the transmit and receive lines are crosslinked. In some
cables there are also handshake lines crosslinked. In many situations a straight
through serial cable is used, together with a null modem adapter. The adapter
contains the necessary crosslinks between the signals.
Pairing
A Bluetooth pairing occurs when two Bluetooth devices agree to communicate with
each other and establish a connection.
