The difference between the highest and lowest frequencies available for network signals. The term
bandwidth
also is used to describe the rated throughput capacity of a given network medium or protocol. For a
digital channel, this is defined in bits. For an analog channel, it depends on the type and method of
modulation used to encode the data.

bps
A device that connects two or more physical networks and forwards packets between them. Bridges
