The maximum rate of information transfer (measured in bits/second) that can be carried by a communication channel.

The useable capacity of a network, normally measured in bits per second (bps)

The nformation carrying capacity of a communication channel.

This is the capacity of a link usually measured in bits-per-second (bps).

The wavelength range or width characterizing a band of a multispectral sensor. For example, the bandwidth of a visible light band (0.38 to 0.8 micron boundaries) would be 0.42 microns.

The width of the passband or the stopband of a filter, normally referenced to the minimum insertion loss point in the passband. For example, the passband of a filter is normally stated as a -3 dB bandwidth and the stopband may be stated as a -40 dB bandwidth.

the width of a band. Units of nm etc. The effective bandwidth, is the width of the band at half-height.

The range of optical wavelengths which can be transmitted through a component. It is the wavelength range, which defines the spectral width of one WDM channel.

(See AUDIO BANDWIDTH and VIDEO BANDWIDTH)

the total rate at which information can be passed down a telecommunications link. Applications such as basic email exchange require lower bandwidth than, for example, audio or video transmission.

Qualitative term describing the video amplifier's potential performance. The higher the pixel rate (or format number), the higher the bandwidth required of the video amplifier.

The number of characters that may be downloaded or uploaded from your site each month

Bandwidth represents the total number of kilobytes that were sent to people visiting your site. Bandwidth includes all resources requested by the users.

Each time someone views a page on your site it has to be sent via telephony to their computer, similarly when you download or send e-mails from your domain, view web statistics etc. The amount of telephony resources (in Megabytes or Gigabytes) that is consumed is counted against your total bandwidth allowance.

Bandwidth is the total number of bytes you use in a month. The easiest way to explain it is with an example. Let's suppose that you have a page with 5,000 bytes of text and 55,000 bytes of graphics, for a total of 60,000 bytes on your page. If you get a 100 hits a day that is 60,000 bytes X 100 or 6 megabytes a day. Now multiply that by 30 days and you get 180 megabytes per month. That's only 3,000 hits in a month (which isn't enough hits to stay in business). Most of the ISP's give you 300 megabytes or so. But what if you have 10 pages the same size or you get 200 hits a day, in both cases you are way over your bandwidth limit.
