bandwidth

Definitions

General English

Astronomy

  • The frequency spread of a signal in any part of the electromagnetic spectrum, expressed in units such as hertz, either as observed in nature or as transmitted by a piece of equipment like a cable, an antenna or a length of optical fibre

Cars & Driving

  • noun a range of audio frequencies an audio component such as a car stereo can handle

Commerce

  • noun a measurement of the capacity of a fibre-optic cable to carry information to and from the Internet

Computing

  • noun a measure of the range of frequencies that a monitor or CRT will accept and display
  • noun a measure of the amount of data that can be transmitted along a cable or channel or other medium

Construction

  • A range of frequencies expressed in cycles per second (hertz). The greater the bandwidth, the more information that can be transmitted.

Electronics

  • An interval of frequencies which is utilized for any given purpose, such as that assigned to a TV transmitter.
  • The difference between the upper and lower frequencies of a continuous frequency band, in which performance falls within certain limits with respect to a given characteristic.
  • The interval of frequencies between which a device can produce a given proportion of its maximum output. Usually calculated at 50% or 90% of full power. Also called bandpass (1).
  • The data transmission capacity of a communications channel, system, network, or medium. May be expressed, for instance, in bits, bytes, or cycles per second.
  • A fraction of bandwidth (4) which is utilized for any given purpose.
  • acronymBW
  • synonymbandpass
  • A band of frequencies which is passed with little or no attenuation, while all others are highly attenuated.

Human Resources

  • noun limits such as upper and lower performance levels or work hours that define a range

Media Studies

  • noun a range of frequencies that is used for radio or telecommunications transmission and reception
  • noun the amount of data, often measured in bits per second, that a communication channel such as an Internet connection, can transmit
