View source for Bandwidth (computing)

In [[computing]], '''bandwidth''' is the bit-rate of available or consumed information capacity expressed typically in metric multiples of bits per second. 

Variously, bandwidth may be characterized as:

* Network bandwidth
* Data bandwidth
* Digital bandwidth

== Bandwidth in other fields ==

The term '''bandwidth''' is used differently in such fields as: 

* Signal processing
* Wireless communications
* Modem data transmission
* Digital communications
* Electronics

In these fields, ''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.

The connection to the computing term is that, according to Hartley's law, the digital data rate limit, or channel capacity, of a physical communication link is proportional to its bandwidth in hertz.
