What is the Difference between HTTP and World Wide Web ?

    When you say, 'the Internet,' what comes to mind for most people is, in fact, the World Wide Web. The World Wide Web, or just the Web, is not the Internet. Instead, it is a method of using the Internet to exchange information between computers. The Web uses http or hypertext transfer protocol and services known as web browsers and web servers to allow information in the form of web pages to be exchanged between local and remote computers.
On the local side, what you see is the web browser. Information from the remote computer is sent to your local computer using the http protocol. The web browser interprets that information and displays it on your local computer in the form of web pages.

The hypertext part of the http protocol refers to a non-linear method of presenting information. Text is normally read in a linear fashion: word 2 follows word 1; sentence 3 follows sentence 2; paragraph 5 follows paragraph 4. The idea of hypertext allows information to be viewed in a non-linear way. This is the major difference between hypertext and the older, plain text methods of displaying information.
With hypertext, words and ideas can connect, not only with the words that directly surround them, but also with other words, ideas or images. Hypertext is not restricted to the Web. Most full-featured word processors will allow you to create locally stored pages in web or http format. These pages are read using your web browser and act as would any other web page, only they are stored on your local computer, not a remote computer.
