The concept of web documentation was developed in 1989, when Tim Berners Lee proposed
the first hypertext system of web documentation. The background concept commenced in
CERN, a practical physics laboratory, in response to a need for sharing documents among
laboratory researchers. The first web was developed using SGML  that is highly dependable
on the DOM . SGML consisted of worldwide set standards of elements that can be
implemented independent of browser or software diversity. Adjoining the elementary purpose
in scientific collaboration, the concept of web was largely accepted when proposed to
computing researchers of the time. Therefore, the first prototype was disseminated and
implemented into practice in 1990. The proposal consisted of three fundamental specifications
that are still promine
nt in today’s web technology.
HTML: serves as a medium language for editing and inserting contents to the web.
URL: is a unique address assigned for each particular resource on the web.
HTTP: applies as the ground application protocol to transfer data between browsers and
HTML5 is a mark-up language that has extended the functionalities of the web, improving the
previous structure of web technology, which reflected a one-way flow of information to the users.
Apart from introducing new semantic features [Appendix I], HTML5 contributes new techniques
on modern and interactive web environment. HTML5 is a product of cooperative work in W3C
In addition, HTML5 tries to balance the compatibly issue of the previous browsers using the
new features. The latest version of web browser from Apple, Safari, Google Chrome, Mozilla
Firefox, Opera full and Internet Explorer 9.0 support HTML5 functionalities.
