Glossary
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.
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.
In a network, the bus (also called the backbone) is the main cable that connects
all devices on a LAN.
byte
Abbreviation for binary term, a unit of storage capable of holding a single
character. On almost all modern computers, a byte is equal to eight bits. Large
amounts of memory are indicated in terms of kilobytes (1024 bytes), megabytes
(1 048 576 bytes), and gigabytes (1 073 741 824 bytes).
C
cache
A temporary storage area in computer memory.
call duration timer
Used in PSTN mode only, it specifies the minimum length of time that each call
to the host PBX remains open, regardless of telephone activity (or lack thereof).
call on demand
A call connection that is opened only when a connection to the host PBX is
required. This is different from a permanent connection, which is open all the
time.
call treatment
A method of handling applied to a call while it is waiting to be answered or
serviced.
