|“||[t]he capacity of a communication channel to pass data through the channel in a given amount of time. . . .||”|
The amount of information or data that can be sent over a network in a given period of time. Bandwidth is usually stated in bits per second (bps), kilobits per second (kbps), megabits per second (mbps) or gigabits per second (gbps)
Bandwidth also refers to the speed at which data can flow through computer and telecommunications networks without interference. Together, latency and bandwidth define the speed and capacity of a network.
Bandwidth also refers to the total width of frequencies, including the sidebands, occupied by a radio signal. In practical terms, however, the bandwidth of a signal refers to the amount of spectrum needed to transmit a signal without excessive loss or distortion. It is measured in hertz. The bandwidth of a radio signal is determined by the amount of information in the signal being sent. More complex signals contain more information, and hence require wider bandwidths.
