band•width (ˈbændˌwɪdθ, -ˌwɪtθ)
n.

2. the transmission capacity of an electronic communications device.
[1925–30]
| bandwidth (bndwdth, -wth) 1. The numerical difference between the upper and lower frequencies of a band of electromagnetic radiation, especially an assigned range of radio frequencies. 2. The amount of data that can be passed along a communications channel in a given period of time. For analog devices, such as standard telephones, bandwith is the range of frequencies that can be transmitted and is expressed in hertz (cycles per second). For digital devices, bandwidth is measured in bits per second. The wider the bandwidth, the faster data can be sent. |
The difference between the limiting frequencies of a continuous frequency band expressed in hertz (cycles per second). The term bandwidth is also loosely used to refer to the rate at which data can be transmitted over a given communications circuit. In the latter usage, bandwidth is usually expressed in either kilobits per second or megabits per second.
