Bandwidth (computing)
In computing, bandwidth is the bit-rate of available or consumed information capacity expressed typically in metric multiples of bits per second.
Description
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.
