be interlinked and accessible over the Internet worldwide. www is also known as

            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.

                USING WEB BROWSER

            For several years, the Web remained a tool used by scientific researchers. But in 1993,

            developers at the National Center for Supercomputing Applications (NCSA)
            created Mosaic, a point and click Web browser. A Web browser is a software
            application designed to find hypertext documents on the Web and then open the
            documents on the user’s computer.  Commonly used web browsers are Google
            Chrome, Microsoft Edge, Mozilla Firefox, etc.
