Query: This book is horrible

Don't waste your money with this book. It is horrible. I can't believe my college uses this as a textbook. Information in the text was incorrect. Come on, it's not hard to put the OSI layer in the correct order. Even found a review question that didn't even have the correct answer as an available choice. I'd like to find an errata, but they don't seem to have one. Don't buy the book.
