bandwidth   (bānd'wĭdth', -wĭth')  Pronunciation Key 
  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.

bandwidth definition


The amount of data that can be carried by a digital communication medium, often expressed in hertz.

Note: Within the radio and microwave portions of the electromagnetic spectrum limited bandwidth is available, and in the United States the use of the spectrum is regulated and allocated by the FCC. (See VHF and UHF.)
