The amount of data that can be sent to your computer over a period of time; usually expressed as kilobits per second (Kbps or thousands of bits per second). The higher the bandwidth, the faster you receive data; similar to using a larger garden hose to get more water faster. Often referred to as bit-rate.
Sometimes this term refers to a range of sound frequencies and is shortened to "band," as in "16-band Equalizer". In this case, the total range of audio frequencies is broken into equal portions, or bands, of sound to be displayed and controlled.
