    World Wide Web

                     The World Wide Web (WWW) is a large information system where you can surf
                     and get information. It consists of several public and private websites, which may
                     be interlinked and accessible over the Internet worldwide. WWW is also known as

                     the Web. Many people believe that the World Wide Web and the Internet are the
                     same thing, but this is not correct. In fact, these are two different things. The Web
                     is a service (a system for accessing information) that is supported by the Internet, a
                     system of interconnected networks.

                     Information on the Web is stored in the form of Web pages.
                     A Web page is a hypertext document. A collection of related

                     web pages is called a website. Websites are housed on Web
                     servers. A Web server is an Internet host computer that
                     often stores thousands of individual Web pages. Copying a
                     Web page onto a server is called publishing the Web page.

                     This process is also called posting or uploading.

                     How Does the Web Work?

                     Web documents can be linked together because they are created in a format known
                     as hypertext. Hypertext  system provides an easy way to manage large collections
                     of data, which can include text files, pictures, sounds, movies and more. To support

                     hypertext documents, the Web uses a special protocol called the Hypertext Transfer
                     Protocol (HTTP). The language allows a document’s author to embed hypertext links,
                     also called hyperlinks or just links, in the document. HTTP and hypertext links are the
                     foundations of the World Wide Web.

                                                                                             Internet and E-mail  45
