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
                 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 hosted on Web servers. A Web server is an Internet host computer that often
                 stores thousands of individual Web pages. Posting a Web page onto a server is
                 called publishing the Web page. This process is also called uploading.

                    HOW DOES THE WEB WORK?

                 Web documents can be linked together  because they are  created  in a format
                 known as hypertext. Hypertext 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). It 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, Safari etc.

                 Launching Your Browser
                                                                                                                   3
                 You need to connect to the Internet before launching the
                 browser. Once you have established a connection, launch
                 your browser by following the given steps:

                 Step 1:  Click on search box.

                 Step 2:  Type the web browser name like microsoft edge.

                 Step 3:   Click  on  Microsoft  Edge. The  Microsoft  Edge
                                                                                           1                 2
                          window will appear.

                                                                                         Internet and E-Mail      63
