Bandwidth (computing)

Common card · No. 271613

In computing, bandwidth is the maximum rate of data transfer across a given path. Bandwidth may be characterized as network bandwidth, data bandwidth, or digital bandwidth. This definition of bandwidth contrasts with usage in signal processing, wireless communications, modem data transmission, digital communications, and electronics, in which bandwidth is used to refer to the signal bandwidth measured in hertz, meaning the frequency range between the lowest and highest attainable frequencies 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.
