3 Principles of Information Systems, Sixth Edition Overview of Telecommunications Systems

4 Principles of Information Systems, Sixth Edition Communications

5 Principles of Information Systems, Sixth Edition Communications

6 Principles of Information Systems, Sixth Edition Telecommunications

7 Principles of Information Systems, Sixth Edition Telecommunications Media

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

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

10 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.

11 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.
