![]() ![]() For example, bandwidth tests measure the maximum throughput of a computer network. The term bandwidth sometimes defines the net bit rate peak bit rate, information rate, or physical layer useful bit rate, channel capacity, or the maximum throughput of a logical or physical communication path in a digital communication system. The actual bit rate that can be achieved depends not only on the signal bandwidth but also on the noise on the channel. This definition of bandwidth is in contrast to the field of signal processing, wireless communications, modem data transmission, digital communications, and electronics, 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. Bandwidth may be characterized as network bandwidth, data bandwidth, or digital bandwidth. In computing, bandwidth is the maximum rate of data transfer across a given path. For other uses, see Bandwidth (disambiguation). For the concept in signal theory and processing measured in hertz, see Bandwidth (signal processing). This article is about use in computing and networking expressed in bits per second. ![]()
