Backplane The data bus connections that interconnects different
communication modules inside a network
concentrator.
BNC A thin Ethernet coax connector.
Bridged Tap (Stub) A cable (or cord) connected to another cable (or cord)
at a point other than its end. Such a tap causes
impairment of network signal transmissions.
Carrier Sense The monitoring of a local area network by a node to
determine if another node is transmitting.
Coaxial Cable A cable with at least one transmission line consisting
of two conductors, an inner conductor, and an outer
conductor insulated from one another by a dielectric.
Coaxial cable carriers higher frequencies than twisted
pair cable and offers a broader bandwidth. It
commonly transmits video signals, but can also be
used for certain high-speed data applications.
Collision A condition that occurs when two nodes attempt to
transmit on the network at the same time. When a
collision occurs, both nodes recognize the collision
stop transmission wait for a random time interval and
then attempt to retransmit.
Concentrator A device that provides connectivity between data
terminals in a network.
Conductor A medium such as copper wire that can carry
electrical current.
Configuration The layout of nodes and components in the network.
Dielectric A substance that does not conduct electrical current.
