Data Communications & Networks: An Engg. Approach

Data Communications and Networks uses a top-down; Internet-focused approach to tackle the problem of communication system design. An integrated approach is taken to networks and data communications, with an emphasis that starts from the top level requirements and works downwards, describing how such requirements are fulfilled by lower layers of the transmission chain. While the book contains sufficient detail to provide an excellent foundation, clarity is paramount and care is taken not to swamp the reader with information to the point where the underlying concepts are obscured.· Communication Systems· The User Perspective· The Security Perspective· The Network Perspective· The Link Perspective· The Channel Perspective· Putting it all together· Answers to Exercises
