bandwidths, plural;
  1. A range of frequencies within a given band, in particular

  2. The range of frequencies used for transmitting a signal

  3. The range of frequencies over which a system or a device can operate effectively

  4. The transmission capacity of a computer network or other telecommunication system

  5. The breadth of a person's interests or mental capacity

  1. a data transmission rate; the maximum amount of information (bits/second) that can be transmitted along a channel
  2. In computer networking and computer science, bandwidth, network bandwidth, data bandwidth or digital bandwidth, is a bit rate measure of available or consumed data communication resources expressed in bits/second or multiples of it (kilobits/s, megabits/s etc).
  3. In mathematics, particularly matrix theory, a band matrix is a sparse matrix whose non-zero entries are confined to a diagonal band, comprising the main diagonal and zero or more diagonals on either side.
  4. Bandwidth is a Canadian radio program, which airs on most CBC Radio One stations in Ontario on Saturday afternoons. The program, produced by CBO-FM in Ottawa, airs in all Ontario markets except Toronto, where CBLA airs its own local production, Big City, Small World, in the same time slot. ...
  5. Bandwidth is the difference between the upper and lower frequencies in a contiguous set of frequencies. It is typically measured in hertz, and may sometimes refer to passband bandwidth, sometimes to baseband bandwidth, depending on context. ...
  6. The width, usually measured in hertz, of a frequency band; Of a signal, the width of the smallest frequency band within which the signal can fit; The rate of data flow in digital networks typically measured in bits per second; The capacity, energy or time required
  7. A measure of capacity of communications media. Greater bandwidth allows communication of more information in a given period of time. ...
  8. The rate of data that can be processed by an Internet connection. The typical unit of measurement is bps (bits per second) or multiples of bits (i.e. kbps/mbps).
  9. How much stuff you can send through a connection. Usually measured in bits-per-second (bps.) A full page of English text is about 16,000 bits. A fast modem can move about 57,000 bits in one second. ...
  10. This refers to data transfer quantity, and is normally referred to in terms of a monthly allocation. You get about 40K page views (including video, audio, text and images) per 1GB of bandwidth. The more hits you get, the bigger bandwidth you need.
  11. The amount of data transferred to and from a web server. Every time a visitor views a file (whether it’s a web page, image, video, or audio file), that file has to be transferred to the visitor’s computer. Bandwidth is the total size of all these files transferred to your visitors’ computers. ...
  12. In audio, the range of frequencies a device operates within. In video, the range of frequencies passed from the input to the output.
  13. The capacity of a telecom line to carry signals. The necessary bandwidth is the amount of spectrum required to transmit the signal without distortion or loss of information. FCC rules require suppression of the signal outside the band to prevent interference.
  14. The difference between the highest and lowest frequencies available for network signals. The term is also used to describe the rated throughput capacity of a given network medium or protocol. ...
  15. Bandwidth or data transfer is the measure of the traffic generated from your website. It is measured in bytes, kilo bytes (KB), mega bytes (MB) or giga bytes (GB).
  16. A measure for the speed (amount of data) you can send through an Internet connection. The more bandwidth, the faster the connection.
  17. The maximum data carrying capacity of a transmission link. For networks, bandwidth is usually expressed in bits per second (bps).
  18. The amount of data that can be transmitted at a given moment to a server. The higher your bandwidth, the larger amount of traffic your site can handle at one time.
  19. We are not pipes that carry data from one location to the next. Instead of "I don't have the bandwidth for that," try "I don't have the time for that," "I'm too busy right now," or how about the direct, "No, I can't do that." Just don't say you have too much on your plate.
  20. The measure of how quickly you can move information from one point to another. If you are using a 14.4 kbps modem, you have at least six times the bandwidth of somebody using a 2400 bps modem. It's similar to roadways - a four-lane highway can carry more traffic than a two-lane highway.
  21. The amount of data that can be transmitted in a fixed amount of time. For digital devices, the bandwidth is usually expressed in bits or bytes per second (bps).
  22. The amount of frequency allocated for an RF transmission. For example, a cellular channel typically has a bandwidth of 30 KHz, I.E. a cellular system requires 30 KHz of frequency per channel to transmit it's signal.
  23. Bandwidth is the measure of network capacity. High bandwidth means high network capacity, in other words, high speed.
  24. The range of frequencies that can pass over a given transmission channel. The bandwidth determines the rate at which information can be transmitted through the circuit: the greater the bandwidth, the more information that can be sent in a given amount of time. ...
  25. The total frequency range of any system. Usually specified as something like: 20-20,000Hz plus or minus 3 db.
