To be strictly fair, I should note only those published at the same time as, or earlier than, the one I'm reviewing. Even with that proviso, I can still say that Tanenbaum's "Computer Networks" (cf. BKCMPNWK.RVW), Stallings' "Data and Computer Communications" (cf. BKDTCMCM.RVW), and Minoli's "Telecommunications Technology Handbook" (cf. BKTLTCHB.RVW) all far exceed Stamper's work. Even McNamara's venerable "Technical Aspects of Data Communications" (cf. BKTCHDCM.RVW) (from 1988) presents a superior picture of basic communications technology. Stamper does try to cover the fundamentals, but even his introduction, in chapter one, is a confusing mix of foundational concepts and irrelevant (and outdated) examples and applications. Chapter two, on the physical and data layers, is reasonable but limited. The discussion of networking, in chapter three, starts off much the same, but soon wanders into trivia. Chapter four, ostensibly about LANs, contains a number of topics (such as backup) that have nothing to do with communications at all, and chapter five seems to be an attempt to duplicate the same material. Chapters six to nine show some awareness of basic concepts of networking and internetworking, but hidden in a confused mass of verbiage and extraneous detail. Some simplistic thoughts on security and data communications applications finish the book in chapter ten. This work is noted to be an "integrated text and software package" on the basis of some slide shows included on the accompanying disk. The slide shows basically reproduce some illustrations included in the book (or, one might say, the book reprints all of the slides). The figures are as non-illuminating as all too many objects of the type. However, when the "computer based training" tries to improve matters with animations, the results are even worse. Where the graphics are simply incomprehensible (unless you already know what is going on), the animations sometimes present material in erroneous ways, seeming to present incorrect ideas and concepts. This book is stated to be a course text. Why anyone would choose it over other available works is beyond my comprehension. copyright Robert M. Slade, 2002 BKESDTCM.RVW 20020628
