With the advent of the World Wide Web the global Internet has rapidly become the dominant type of computer network. It now enables people around the world to use the Web for E-Commerce and interactive entertainment applications, in addition to those already supported by the Internet such as e-mail and IP telephony. As a result, the study of computer networking is now synonymous with the study of the Internet and its applications. The 5th edition of this highly successful text has been completely revised to focus entirely on the Internet, and so avoids the necessity of describing protocols and architectures that are no longer relevant. As many Internet applications now involve multiple data types ¿ text, images, speech, audio and video ¿ the book explains in detail how they are represented.

A number of different access networks are now used to gain access to the global Internet.  Users at home and in small businesses gain access through their local switched telephone network using either a low bit rate or broadband modem.  For users served by a cable television provider, access is often through a high bit rate cable modem. Wireless networks are now widely used including Internet-enabled mobile phones with cellular phone networks and, within buildings, wireless networks such as Bluetooth. These are in addition to the site networks used by academic institutions and large businesses.  Separate chapters illustrate how each type of access network operates and interfaces to the global Internet.  This is followed by a detailed account of the architecture and protocols of the Internet itself and the operation of the major application protocols.

This body of knowledge is made accessible by extensive use of illustrations and worked examples that make complex systems more understandable at first glance.  This makes the book ideal for self-study or classroom use for students in Computer Science or Engineering, as well as being a comprehensive reference for practitioners who require a definitive guide to networking.

New in this edition:

• A separate chapter is devoted to each of the different types of access network: Telephone networks, LANs and intranets, Wireless networks, and Entertainment networks.
• A chapter is devoted to each of the main components of the global Internet, from modern Internet protocols to the World Wide Web.
• A whole chapter is devoted to the vital topic of Network Security.
• An online study guide provides a rich set of resources for both students and instructors: check out www.pearsoned.co.uk/halsall

As the cliché reminds us, information is power. In this age of computer systems and technology, an increasing majority of the world's information is stored electronically. It makes sense then that as an industry we rely on high-tech electronic protection systems to guard that information. As a professional hacker, I get paid to uncover weaknesses in those systems and exploit them. Whether breaking into buildings or slipping past industrial-grade firewalls, my goal has always been the same: extract the informational secrets using any means necessary. After hundreds of jobs, I discovered the secret to bypassing every conceivable high-tech security system. This book reveals those secrets, and as the title suggests, it has nothing to do with high technology. As it turns out, the secret isn't much of a secret at all. Hackers have known about these techniques for years. Presented in a light, accessible style, you'll get to ride shotgun with the authors on successful real-world break-ins as they share photos, videos and stories that prove how vulnerable the high-tech world is to no-tech attacks.

As you browse this book, you'll hear old familiar terms like "dumpster diving", "social engineering", and "shoulder surfing". Some of these terms have drifted into obscurity to the point of becoming industry folklore; the tactics of the pre-dawn information age. But make no mistake; these and other old-school tactics work with amazing effectiveness today. In fact, there's a very good chance that someone in your organization will fall victim to one or more of these attacks this year. Will they be ready?

Although the World Wide Web is enjoying enormous growth rates, many Web publishers have discovered that HTML is not up to the requirements of modern corporate communication. For them, Adobe Acrobat offers a wealth of design possibilities. The close integration of Acrobat in the World Wide Web unites the structural advantages of HTML with the comprehensive layout possibilities of Portable Document Format (PDF). On the basis of practical examples and numerous tricks, this book describes how to produce PDF documents efficiently. Numerous tips on integrating Acrobat into CGI, JavaScript, VBScript, Active Server Pages, search engines, and so on make the book a mine of information for all designers and administrators of Web sites.

The Encyclopedia of Algorithms aims to provide the researchers, students, and practitioners of algorithmic research with a mechanism to efficiently and accurately find the names, definitions, key results, and further readings of important algorithmic problems.

The work covers a wide range of algorithmic areas, and each algorithmic area is covered by a collection of entries. An encyclopedia entry is an in-depth mini-survey of an algorithmic problem and is written by an expert researcher. The entries for an algorithmic area are compiled by an area editor to survey the representative results in that area and can form the core materials of a course in the area.

The Encyclopedia does not use the format of a conventional long survey for several reasons. A conventional survey takes a handful of individuals too much time to write and is difficult to update. An encyclopedia entry contains the same kinds of information as in a conventional survey, but an encyclopedia entry is much shorter and is much easier for readers to absorb and for editors to update. Furthermore, an algorithmic area is surveyed by a collection of entries which together provide a considerable amount of up-to-date information about the area, while the writing and updating of the entries is distributed among multiple authors to speed up the work.

This reference work will be updated on a regular basis and will evolve towards primarily an Internet-based medium to allow timely updates and fast search. If you have feedback regarding a particular entry, please feel free to communicate directly with the author or the area editor of that entry. If you are interested in authoring an entry, please contact a suitable area editor.

The credit of the Encyclopedia goes to the area editors, the entry authors, the entry reviewers, and the project editors at Springer, including Jennifer Evans and Jennifer Carlson.

Ruby on Rails continues to build up a tremendous head of steam. Fueled by significant benefits and an impressive portfolio of real-world applications already in production, Rails is destined to continue making significant inroads in coming years.

Each new Rails application showing up on the web adds yet more to the collective wisdom of the Rails development community. Yesterday's best practices yield to today's latest and greatest techniques, as the state of the art is continually refined in kitchens all across the Internet. Indeed, these are times of great progress.

At the same time, it's easy to get left behind in the wake of progress. Advanced Rails Recipes keeps you on the cutting edge of Rails development and, more importantly, continues to turn this fast-paced framework to your advantage.

Advanced Rails Recipes is filled with pragmatic recipes you'll use on every Rails project. And by taking the code in these recipes and slipping it into your application you'll not only deliver your application quicker, you'll do so with the confidence that it's done right.
