bit
Short for binary digit, the smallest unit of information on a machine. A single bit
can hold only one of two values: 0 or 1.
Boolean logic
A logic system that enables a computer to use electricity to make complex
decisions. The basic logic gates (And, Or, and Not) determine the flow of
electricity through the computer’s circuitry and whether specific computing
functions are carried out.
boolean
A value that can only be true or false.
branch station
A telephone set located at the Remote Gateway 9110, 9115, 9150, or Digital
Telephone IP Adapter site.
BRI

bridge
A protocol-independent device that connects two LANs or two segments of the
same LAN. Bridges are faster (and less versatile) than routers because they
forward packets without analyzing and rerouting messages.
bridge port
Bridge ports are configured on the Remote Gateway 9150 unit and are used to
connect branch office trunks through the host PBX to accommodate conference
calls, remote station to remote station calls, and so on.
bus
A collection of wires that connects the microprocessor and main memory to
internal computer components. All buses consist of an address bus that transfers
data and a data bus that transfers information about where the data should go.
