The World Wide Web (also called WWW, or W3 or simply the Web) is a tool that helps you to find and retrieve information, using links to other WWW pages. Web links are stored within the page itself and when you wish to "jump" to the next page that is linked, you select the "hotspot" or "anchor". This technique is sometimes called hypermedia or hypertext. We already have used hypertext in Windows based Help system. When we click on some underlined words, they lead us to a different topic. These underlined words are said to be in hypertext. The organization that maintains the standards that enable us to use the WWW is called the World Wide Web Consortium.
WWW clients on the Internet can display pages from any of the nearly 1 million Web servers. Each time you choose a link; WWW connects to the appropriate server, retrieves the next page wanted, and returns control to the local client. Once the document has been retrieved, the link is broken. This means that the server does not have to keep the link open while you read the document. WWW is thus an efficient method of finding and using information widely dispersed throughout the world.
World Wide Web is a system of Internet servers that support specially formatted documents. The documents are formatted in a language called HTML (Hyper Text Markup Language) that supports links to other documents, as well as graphics, audio, and video files. This means one can jump from one document to another simply by clicking on hot spots. Not all Internet servers are part of the World Wide Web. Access to the Web is accomplished through a Web browser (e.g., Netscape Navigator, Microsoft Internet Explorer).
