To say that the Internet has changed our lives, however, is not to say that the transformation is complete. Software developers are inventing new uses for the Internet all the time. Many of these uses, such as real-time video displays, require a great deal of speed from Internet connections. Even older uses, such as transferring ordinary files, increasingly require fast Internet connections, as the size of those ordinary files increases. For this reason, much future development of the Internet will require higher-speed access than many users currently have. Conventional telephone modems are limited to 56 kilobits per second (Kbps) speed, and that limit isn't likely to increase for technical reasons.
Enter broadband. This word has different meanings to different people, but in this book it refers to high-speed Internet access delivered to businesses and homes. Broadband can take many different forms, including digital subscriber line (DSL) over telephone lines, cable modems, various optical fiber technologies, satellite transmissions, and local radio transmissions. No matter the form, though, broadband holds the promise to take the Internet to the next levelone in which real-time video transfers, quick downloads of large files, and more are all possible. Broadband technologies also usually allow full-time connection to the Internet, which enables the running of serversprograms that respond automatically to requests presented by other computers. Running personal servers opens up new possibilities for interaction with others, such as giving employees or friends the ability to use a computer remotely. Broadband connections are more effectively shared among several computersa fact that will become more important in the future, as currently isolated appliances sprout networking features. (Imagine a radio-like device that can download music from the Internet, or a refrigerator that can report on its contents when you're at work.)
Those of us who have broadband connections today can experience many of the benefits of improved Internet speed already. (I haven't yet seen any network-enabled refrigerators, although I've heard of soft drink vending machines with Internet connections.) In many ways a broadband connection works just like a dial-up modem connectionyou can browse the Web, download files, send e-mail, and so on using either connection. Broadband, though, opens up enough new possibilities that broadband subscribers can use a practical guide to the technology. That's where this book comes in.
Are you interested in using a broadband connection, but don't know what form to get? Do you have a broadband connection and want to learn how to do more with it than simply browse the Web at high speed? If you answered yes to either of these questions, this book can help.
I wrote this book as an end-user guide to broadband. There are many books available on the technical details of DSL, cable, satellite, and other forms of broadband, but most of these are intended for the people who work with the networking hardware, or who operate businesses that work closely with these technologies. This book is different because it focuses on what you as a consumer need to know to order broadband service and make use of it. The focus is on broadband as a networking technology. It's possible to get video and telephone service through many broadband connections, but these issues are peripheral to this book's focus. As described shortly, this book's topics include an overview of different broadband technologies, configuration, running servers, sharing your connection, and security. I wrote this material with end users in mind, not network professionals who must master the details of different modulation schemes or the like. This book does not focus on uses of the Internet that are common on slower connections, such as Web browsing; it's intended to describe what you can do with a broadband Internet connection that can't be done with a dial-up telephone link.
I've tried to keep the needs of both business and residential users in mind when writing. In many cases, the needs of both overlap, but sometimes there's deviation. The chapter on game servers, for instance, isn't likely to interest many businesses. Whenever some feature has differing implications for business as opposed to residential users, I point it out.
If you use Windows as your primary operating system, you will of course find information on how to use it with a broadband connection. I've included coverage of both the Windows 9x/Me and NT/2000 lines. I haven't stopped there, however; this book also covers MacOS (both the older Classic versions and the new MacOS X, which is based on Unix) and Linux. For the most part, broadband principles apply across all platforms; it's implementation details, such as how to run specific programs, that differ from one to another. When necessary, I present examples in each of the OSs. Sometimes tools work very similarly across platforms, so I use just one as an example.
For the most part, discussions of how to use broadband apply equally well to all forms of broadband. For instance, software to perform network address translation (NAT) works the same on DSL, cable, or any other type of connection. You'll therefore find most of this book applicable no matter what form of broadband you use. The chapters describing specific technologies are, of course, exceptions to this rule.
This book is organized into five parts, plus appendices and a glossary:
In addition to these major sections, a glossary describes common broadband-related terms with which you may not be familiar. These terms are described in the text proper, but the glossary can be much more convenient if you run across a term and don't recall where it was originally defined.
You shouldn't feel compelled to read the chapters in order. As a practical matter, you'll need to either read Parts I and II or already know most of this material before proceeding to subsequent chapters. Parts III, IV, and V can be read in any order, or you can skip entire chapters or even parts. When a chapter assumes knowledge of some topic, it includes an appropriate cross-reference.

I'd like to thank my editor, Stephane Thomas, for her careful work shepherding this book through the production process. The book's reviewers, John J. Brassil, Jonathan Fellows, Will Kelly, Al Vonkeman, and one anonymous person, deserve thanks for pointing out additional information and areas where the manuscript could be improved. I'd also like to thank David King for invaluable discussions and pointers to additional information. Finally, I'd like to thank my agent, Neil Salkind of Studio B, for helping find the best home for this book at Addison-Wesley.
