In computer networking and computer science, bandwidth, network bandwidth, data bandwidth or digital bandwidth, is a bit rate measure of available or consumed data communication resources expressed in bits/second or multiples of it (kilobits/s, megabits/s etc).
Note that in textbooks on data transmission, digital communications, wireless communications, electronics, etc, bandwidth refers to analog signal bandwidth measured in hertz - the original meaning of the term. Some computer networking authors prefer less ambiguous terms such as bit rate, channel capacity and throughput rather than bandwidth in bit/s, to avoid this confusion.
