Query: A+ in the NW and Data Comm hard to find books.

The subject of Networking and Data communication is hard to teach and the good books are also hard to find.For anyone interested in the details of Networking and its mathematical and logical scales, there is no other book that represents this wide subject in an easy to read, understand and comprehend the subject. Although this is only my second required textbook in the Networking and Data communication, one undergrad and now grad school, it is my ...probably 10th book to read/use as a reference in my daily tasks.All or partial of the text might be presented as grad level course or subject, but it is presented in a simple way. Go ahead, read it...you buy it or borrow it at the local library you won't be disappointed.TL
