What is a Bandwidth ?
Bandwidth
Bandwidth, in a general sense, is a term that describes information-carrying capacity. It can apply to telephone or network wiring as well as system data buses, radio frequency signals, and monitors. On a more human level, the term can describe a person's capacity by dealing in multiple projects ("I'd like to update this database, but I don't have the bandwidth."). Bandwidth is most accurately measured in cycles per second, or hertz (Hz), which is the difference between the lowest and highest frequencies transmitted. But it's also common to use bits or bytes per second instead.
Bandwidth n.
Broadband adj
[common] Used by hackers (in a generalization of its technical meaning) as the volume of information per unit time that a computer, person, or transmission medium can handle. "Those are amazing graphics, but I missed some of the detail -- not enough bandwidth, I guess." Compare low-bandwidth. This generalized usage began to go mainstream after the Internet population explosion of 1993-1994.
Attention span.
On Usenet, a measure of network capacity that is often wasted by people complaining about how items posted by others are a waste of bandwidth.
Of or relating to or being a communications network in which the bandwidth can be divided and shared by multiple simultaneous signals (as for voice or data or video)
responding to or operating at a wide band of frequencies; "a broadband antenna" [syn: wideband]
[communications] A transmission medium capable of supporting a wide range of frequencies, typically from audio up to video frequencies. It can carry multiple signals by dividing the total capacity of the medium into multiple, independent bandwidth channels, where each channel operates only on a specific range of frequencies.
Bandwidth = Maximum Throughput / Transmitting Nodes
