The uses of computer systems right this moment are as numerous because the types of computer systems that exist available in the market. 2) In digital communication, bandwidth is the width of the range (or band ) of frequencies that an electronic sign uses on a given transmission medium. On this utilization, bandwidth is expressed by way of the distinction between the very best-frequency sign part and the bottom-frequency sign part. Since the frequency of a sign is measured in hertz (the variety of cycles of change per second), a given bandwidth is the difference in hertz between the very best frequency the signal makes use of and the bottom frequency it uses. A typical voice signal has a bandwidth of approximately three kilohertz (3 kHz ); an analog television (TV) broadcast video signal has a bandwidth of six megahertz (6 MHz ) – some 2,000 instances as large because the voice sign.
