This textbook presents computer networks to electrical and computer engineering students in a manner that is clearer, more interesting, and easier to understand than other texts. All principles are presented in a lucid, logical, step-by-step manner. As much as possible, the authors avoid wordiness and giving too much detail that could hide concepts and impede overall understanding of the material. Ten review questions in the form of multiple-choice objective items are provided at the end of each chapter with answers. The review questions are intended to cover the little "tricks" which the examples and end-of-chapter problems may not cover. They serve as a self-test device and help students determine how well they have mastered the chapter.
