Bandwidth

The available space between two given points on the electromagnetic spectrum and, inter alia, the amount of information that can be squeezed into that space.

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.
