Building on the successful top-down approach of previous editions, the Fourth Edition of Computer Networking continues with an early emphasis on application-layer paradigms and application programming interfaces, encouraging a hands-on experience with protocols and networking concepts. With this edition, Kurose and Ross bring the issues of network security to the forefront, along with integration of the most current and relevant networking technologies.

Computer Networks and the Internet; Application Layer; Transport Layer; The Network Layer; The Link Layer and Local Area Networks; Wireless and Mobile Networks; Multimedia Networking; Security in Computer Networks; Network Management.

For all readers interested in computer networking technologies.

Certain data-communication protocols hog the spotlight, but all of them have a lot in common. Computer Networking: A Top-Down Approach Featuring the Internet explains the engineering problems that are inherent in communicating digital information from point to point. The top-down approach mentioned in the subtitle means that the book starts at the top of the protocol stack--at the application layer--and works its way down through the other layers, until it reaches bare wire.

The authors, for the most part, shun the well-known seven-layer Open Systems Interconnection (OSI) protocol stack in favor of their own five-layer (application, transport, network, link, and physical) model. It's an effective approach that helps clear away some of the hand waving traditionally associated with the more obtuse layers in the OSI model. The approach is definitely theoretical--don't look here for instructions on configuring Windows 2000 or a Cisco router--but it's relevant to reality, and should help anyone who needs to understand networking as a programmer, system architect, or even administration guru.

The treatment of the network layer, at which routing takes place, is typical of the overall style. In discussing routing, authors James Kurose and Keith Ross explain (by way of lots of clear, definition-packed text) what routing protocols need to do: find the best route to a destination. Then they present the mathematics that determine the best path, show some code that implements those algorithms, and illustrate the logic by using excellent conceptual diagrams. Real-life implementations of the algorithms--including Internet Protocol (both IPv4 and IPv6) and several popular IP routing protocols--help you to make the transition from pure theory to networking technologies. --David Wall

Topics covered: The theory behind data networks, with thorough discussion of the problems that are posed at each level (the application layer gets plenty of attention). For each layer, there's academic coverage of networking problems and solutions, followed by discussion of real technologies. Special sections deal with network security and transmission of digital multimedia.

Updated to include all the recent developments to the PC and complete with a CD-ROM, the third edition of How Computers Work is like a cool science museum in a book. But make no mistake--this is not a book for children. How Computers Work aims to teach readers about all the intricacies held within the machine, and it's a daunting task. The author, Ron White, doesn't dumb down his material; instead he provides thorough and substantive definitions. The pages of fun and colorful graphics ease the tension, though, and bring the abstract concepts--the difference between RAM and ROM, for example--into real life.

The book has incredible depth, explaining everything you could want to know about your computer, with each piece of hardware being given full treatment over two to five pages. (Macintosh and UNIX users should be aware, though, that the book's model is the "Wintel," a Windows PC with an Intel microprocessor.) The book is well-structured and can easily be used as a reference resource beyond the first reading. --Jennifer Buckendorff
