Bandwidth is a term used in computing and networking to describe the maximum rate of data transfer across a given path). It is the amount of data that can be transmitted in a specified amount of time. Bandwidth is not a measure of network speed, but rather describes data transfer rate. It is often mistaken for internet speed when its actually the volume of data transmitted over an internet connection in a given amount of time.
Bandwidth can be characterized as network bandwidth, data bandwidth, or digital bandwidth). Network bandwidth is a measurement indicating the maximum capacity of a wired or wireless communications link to transmit data over a network connection. Data bandwidth refers to the amount of data that can be transmitted over a given medium). Digital bandwidth is used to refer to analog signal bandwidth measured in hertz, meaning the frequency range between the lowest and highest attainable frequency while meeting a well-defined impairment level in signal power).
Bandwidth is measured in bits, kilobits, megabits, or gigabits that can be transmitted in one second. Effective bandwidth, which is the highest reliable transmission rate a link can provide on any given transport technology, can be measured using a bandwidth test. The actual bit rate that can be achieved depends not only on the signal bandwidth but also on the noise on the channel).
In summary, bandwidth is the maximum amount of data that can be transmitted over a network connection in a given amount of time. It is not a measure of network speed, but rather describes data transfer rate. Bandwidth can be characterized as network bandwidth, data bandwidth, or digital bandwidth. It is measured in bits, kilobits, megabits, or gigabits that can be transmitted in one second.
