                  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.

                      HTML


                  HTML stands for Hypertext Markup Language. It is a markup language that describes the
                  structure of a web page. It allows us to create web pages that contain paragraphs, headings,
                  links and block quotes. The output of HTML web pages is same on any type of computer and

                  on any operating system, e.g., MacOS, Windows, etc. HTML5 was issued/released as a W3C
                  Recommendation in 2014.

                   HTML  was  created  by  Tim  Berners-Lee  in  early  1990s  but  was  not  officially  released.
                   It  was  published  in 1995 as  HTML  2.0.  It  is a  subset of  Standard  Generalized  Markup
                   Language (SGML).
