  • /ˈbændwɪdθ/
  • /ˈbændwɪtθ/

Where it comes from

From band + width.

noun bandwidths

  1. countable, uncountable The width, usually measured in hertz, of a frequency band. But now is a good time to be bargaining for bandwidth, as the switch from analogue to digital television is freeing up space.
  2. countable, uncountable, of a signal The width of the smallest frequency band within which the signal can fit.
  3. countable, informal, uncountable The rate of data flow in digital networks typically measured in bits per second; the bitrate. While comm buoys allow rapid transmission, there is a finite amount of bandwidth available. Given that trillions of people may be trying to pass a message through a given buoy at any one time, access to the network is parceled out on priority tiers.
  4. countable, informal, uncountable The capacity, energy or time required. I think it's a worthy project, but I just don't have the bandwidth right now.
  5. countable, uncountable The minimum, over all orderings of vertices of a given graph, of the length of the longest edge.
