broadband

Network transmission capacity that greatly exceeds capacity required for voice transmission over traditional telephone cables. Broadband networks may have dedicated portions for audio, video, and data or they may allow for capacity switching. (See also Bandwidth, Information highway, Switched network, Networks, and ATM)

A transmission medium capable of supporting a wide range of frequencies. It can carry multiple signals by dividing the total capacity of the medium into multiple, independent bandwidth channels, where each channel operates only on a specific range of frequencies. See also: baseband.

When the bandwidth of a signal is large,it can simultaneously carry many channels of information.Fiber optic cable,in particular,has a very high bandwidth,and is referred to as broadband

This term refers to high-speed data transmission in which a single cable can carry several channels of data at once. The most common type of broadband transmission is cable wiring (as in cable TV and cable modems). Because of its multiogy mosple channel capability, broadband has started to replace the baseband, or single-channel technolt computer networks were orginially based on. So now when you see companies like AT&T and MediaOne pushing those fancy broadband ads in your face, you'll at least know what they're talking about.
