The World Wide Web (WWW), or Web, a widely used service on the Internet, consists of a worldwide collection of electronic documents. Each electronic document on the Web, called a Web page, can contain text, graphics, animation, audio, and video. Additionally, Web pages usually have built-in connections to other documents. A Web site is a collection of related Web pages and associated items, such as documents and pictures, stored on a Web server.

A Web server is a computer that delivers requested Web pages to your computer. Some industry experts use the term Web 2.0 to refer to Web sites that provide a means for users to share personal information (such as social networking Web sites), allow users to modify Web site content (such as wikis, which are discussed later in this chapter), and have application software built into the site for visitors to use (such as e-mail and word processing programs).

Have a look on this example such as www.abc.org, www2.abc.org, and www3.abc.org the series can be continued www4 www5 etc. Websites like these are mirrors which are used for load balancing the server.
