Data communications and networking

Data Communications and Networking, 3/e provides a comprehensive and current introduction to networking technologies. The book is accessible to students from all backgrounds and uses hundreds of figures to visually represent concepts. The new edition has been completely updated to reflect the constantly changing world of network technologies. Enhanced coverage of bluetooth, wireless, satellites, as well as four new chapters on security have been added.

The third edition has transitioned from using the 7-layer OSI model to the 5-layer Internet Model. More time is spent on TCP/IP in the new organization.

Forouzans book continues to be supported by an On-line Learning Center (OLC) that contains many extra resources for students and instructors. Some of the features include PowerPoints, solutions, self-quizzing, and Flash animations that illustrate concepts.
