Chapter Profile
                 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.


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



                                                                              3   Click on Microsoft
                                                                             Edge. The Microsoft
                                                                             Edge window will appear.










                                 1   Click on search box.                    2   Type Microsoft Edge.



                        USING URLs

                 You have learnt in the previous class that every Web page has a unique address, called a Uniform
                 Resource Locator, or URL. URLs help you to navigate the web. When you provide a URL to the
                 browser, the browser finds that URL’s Web page and then transfers the Web page to your PC. The
                 content of the web page then appears in the Web browser window. You can specify a URL in several
                 ways, but two methods are commonly used. Let us discuss about them.
