Removing this redundant data allows for data compression in a digital system. A digital communication technique which uses packet switching for transmitting data over a network, usually using fibre-optic cable. Its benefits include high speed and high bandwidth , allowing transmission of video data. The capacity of a transmission system to carry information. Bandwidth is related to the amount of the electro-magnetic spectrum that is used or required.
Television requires a much greater bandwidth than radio because there is more information to convey.
Total bandwidth is ultimately limited by the electro-magnetic spectrum. A nought or one, used to represent an on or off state in a digital computer. The smallest unit of data in a digital system. A transmission system with sufficient bandwidth to carry high quality, full-motion video. Contrasts with Narrowband .
