                 Computers connected  to  the  network  (Internet)  are  either  servers  or  clients, and  they
                 communicate with each other through networking protocols. The clients send requests to the

                 servers, and the servers respond immediately with the required data.
                 The server stores the files and information in the form of websites. A website is a collection of

                 web pages. A web page is a document that contains text, graphics, videos, audio, and links to
                 other pages. Every web page of a website has a unique address called the Uniform Resource
                 Locator (URL). This URL allows us to access any web page from anywhere in the world. Have you
                 ever wondered how these web pages are created? HTML is the most widely used language to

                 design web pages.
