Rate at which electronic signals can travel through a medium, such as a wire, cable, or channel. Bandwidth may be thought of as the width of the 'pipe' through which data travels: greater the width, larger the amount of data that can flow through it. Technically, it means the difference between two frequencies. In analog transmission bandwidth is measured in cycles per second (or Hertz); for example, a telephone conversation requires about 4,000 Hertz (4KHz) of bandwidth.
