We are pleased to present this edition of Forouzan’s Data Communications and Networking. It has been developed specifically to meet the need of students of computer networks. In addition to a chapter on the peer-to-peer paradigm, a full chapter on quality of service (QoS), generous coverage of forward error correction, coverage of WiMAX, and material on socket-interface programming in Java, we have added new end-of-chapter questions and problems to make the content more relevant and improve learning outcomes for the student.

Salient features:

• Follows a Visual approach which gives the reader the opportunity to understand the networking concept with real-life application orientation.
• Coverage of encryption, security, and synchronization in multi-processor systems is included with up-to-date information in the field.
• Demonstrate key issues concerning concepts and techniques through examples and case-studies.
