Hypertext Markup Language plays a vital role on the web because of few but significant reasons. First and foremost, Hypertext Markup Language is the foundation or back bone of any webpage. Without HTML, web pages would be nothing but a blank page. Because of this, HTML is called as one of the most important, or probably the most significant part of a webpage. Moreover, in order for the web to function fully, all computers on the web must understand everybody else. Imagine if two separate computers cannot understand each other as each of them speaks different languages – or more precisely, if an individual's web navigation software cannot comprehend another computer's hypertext, all the information it holds are just garbage and useless. To relieve this issue of unsuitability, researchers came up with a standard generalized markup language that is HTML. .
Because of the success of the web and its official markup language, the World Wide Web became extremely helpful to everyone because of all the compilation of information it holds. It is safe to compare web to an online library as it holds almost all the necessary information people need in their everyday lives. One example of this is daily news. Back in the old days, people need to buy newspapers to know what is going on in their city or state. Now, thanks to web, people can access daily news not only for the city they live in, but also news all around the world. Another example of web as a source of information is that people can get references via web. These references includes fee based and free based encyclopedias and dictionaries such as Oxford English Dictionary and Columbia Encyclopedia. The physical versions of these things were used before for doing research and alike. Now, people do not need to carry heavy encyclopedia books because of the web. Finally, information for traveling can be accessed on the web. People now can book airline flights, rent cars, reserve hotel rooms and many more (Mitra, N.
