                                COMMONLY USED INTERNET TERMS

                      Let's learn some commonly used terms on the Internet:

                      WWW

                      The  World Wide Web is  a storehouse  of information.  It is  the  largest  collection  of
                      information which is stored in the form of websites. The web pages on the World Wide

                      Web are developed using a special language called HTML (Hypertext Markup Language).

                      WEB BROWSER

                      A  web browser is  a  software  that  lets  you  access
                      the pages on the World Wide Web. Mosaic was the

                      first successful graphical web browser developed by
                      Marc  Andreessen  and  Eric  Bina  released  in  1993.           Microsoft      Google       Mozilla
                      Microsoft Edge, Google Chrome and Mozilla Firefox                  Edge         Chrome       Firefox
                      are the commonly used web browser.

                      WEB PAGE

                      The pages that make up the World Wide Web are known as web pages. A web page is

                      created using a special language called HTML (HyperText Markup Language). A web
                      page can be accessed using a web browser.

                           PURE        The first web page went live on August 6, 1991. It was dedicated to provide information
                           FACT        on the World Wide Web project and was made by Tim Berners-Lee.

                      HYPERLINK

                      A web page may contain links to other web pages or places. These links are known as
                      hyperlinks. A hyperlink can be a text or a picture. The mouse takes the shape of a hand

                      when we hover it over a hyperlink. When a hyperlink is clicked, the part that it is linked to
                      opens in the browser window.
