This book by tannebaum is the most best seller in the history of computer networks.This book provides information how network works inside.This book include all most popular internet application protocols.Tcp/ip is clearly illustrated.The book covers the concepts wireless technologies, www and its protocols, network security, ISDN, ATM, congestion control algorithms, etc.narration is little diffcult to understand for me.Diagramatic explianation is excellent.
I suggest this book from bottom of my heart.But if u r a beginner it is not a great idea.I suggest DATA COMMUNICATIONS AND NETWORKING BY FOROUZAN than tannenbaum's book.I hope that this information is useful .Thank you for viewing.
