Principles of Information Systems, Sixth Edition Basic Communications Channel Characteristics Simplex channel Half-duplex Full-duplex channel

Principles of Information Systems, Sixth Edition Bandwidth The range of frequencies that an electronic signal occupies on a given transmission medium.

Principles of Information Systems, Sixth Edition Broadband Telecommunications in which a wide band of frequencies is available to transmit information, allowing more information to be transmitted in a given amount of time.

Principles of Information Systems, Sixth Edition Shannon’s Fundamental Law of Information Theory The information carrying capacity of a channel is directly proportional to its bandwidth - the broader the bandwidth, the more information that can be carried.
