The Internet began 25 years ago as a research project for the U.S. Department of Defense and later gained popularity at universities. The World Wide Web contains the multimedia portion of the Internet, where businesses can build their Web sites. As Jill H. and Matthew V. Ellsworth explain in their book, The New Internet Business Book (John Wiley & Sons, $24.95, http://www.wiley.com or 800-JWILEY-NET), "The Web is made up of documents on computers throughout the world. These documents have special codes written into them that provide links to other documents on the Internet and dictate how the documents are to be displayed. Computers holding these Web documents use software called Web servers to communicate via the Internet with client programs that are called browsers."
Browsers, which are software packages, act as a link between the Internet, the Web server and your computer (via its modem) so you can access Internet information. For more information about browsers, consult the HotWired site (http://www.hotwired.com/).
