Kurose and Ross's Computer Networking has been the go-to text for students of computer science and electrical engineering for two decades. It was the first of its kind to approach the subject from a top-down perspective, introducing a new pedagogica) approach, and has continued to incorporate new information as the field of networking has matured. The eighth edition of Computer Networking carries forward that tradition with its top-down approach, its focus on the Internet, its modem treatment of computer networking, its attention to both principles and practice, and its accessible style-all with a fresh and timely approach to the subject.
