Meaning of BROADBAND in English
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.
