I was expecting to find out what TCP/IP was, how it differed from other networking standards, and an explanation of when and how to use the various components. I was disappointed. It took a lot of reading of OTHER material on TCP, and an explanation from a Stanford professor, before I could understand this book.
The book could do with editing to check the topic sequence. Often a term is introduced without explanation as if you know what the author means. The explanation MAY come several pages later.
