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.
