HTML stands for Hypertext Markup Language. The word Hypertext was first
coined by Ted Nelson in 1960s. Markup language is a technique to write
documents, describing the general structure of the contents inside the
documents and not its actual appearance on the page or on the screen.
HTML allows user to link several related information already stored in the
computer or server that can be accessed from anywhere around the world.
Tim Berners Lee developed the HTML standard in 1989, and invented the
world wide web in 1991.
