Bandwidth (computing) Maximum rate of data transfer This definition of bandwidth is in contrast to the field of signal processing, wireless communications, modem data transmission, digital communications, and electronics,[citation needed] in which bandwidth is used to refer to analog signal bandwidth measured in hertz, meaning the frequency range between lowest and highest attainable frequency while meeting a well-defined impairment level in signal power.
The actual bit rate that can be achieved depends not only on the signal bandwidth but also on the noise on the channel. Network capacity[edit] Network consumption[edit] The consumed bandwidth in bit/s, corresponds to achieved throughput or goodput, i.e., the average rate of successful data transfer through a communication path. Channel bandwidth may be confused with useful data throughput (or goodput). For example, a channel with x bit/s may not necessarily transmit data at x rate, since protocols, encryption, and other factors can add appreciable overhead.
