The World Wide Web is an Internet service, based on a common set of protocols, which allows a particularly configured server computer to distribute documents across the Internet in a standard way. This Web standard allows programs on many different computer platforms (such as UNIX, Windows 95, and the Mac OS) properly to format and display the information served. These programs are called Web browsers.

Probably the most important thing to remember about the World Wide Web and the Internet in general is that they are global in scale and often a very cooperative venture. Information on the Web tends to be distributed around the world, and it's just as easy for you to access a site in New Zealand or Japan as it is to access Web information in your own state.

The basic reason for learning HTML is to create pages for the World Wide Web. Before you start, though, you'll want to know a little about how this whole process works. We'll begin by taking a look at Web browsing programs, then we'll talk about how the World Wide Web works, and we'll discuss some of the terms associated with surfing the Web. Finally, we'll round out the discussion by talking about the Internet in general and the different services available on the Internet and how they interact with the Web.

What is a Web Page?
The World Wide Web is composed of millions of Web pages, each of which is served to a browser (when requested) one page at a time. A Web page is generally a single HTML document, which might include text, graphics, sound files, and hypertext links.

What is Web Site?
A Web site can be definded a well organised collection of Web pages under the developed/programmed by a person or group. Generally, a Web site offers a certain amount of organization of its internal information. A web site generally starts with an index.html or default.html page for a Web site, then use hypertext links to other pages in order to access more detailed information. Although, the extensions of these pages may verry as morfe and more programming languages and standards are deleoped. Another page within the Web site may offer links to other interesting sites on the Web, information about the organization, or just about anything else.
