HTML. HTML (Hyper Text Markup Language), it isnt a programming language; it is a markup language, which uses markup tags to make webpages. HTML tags(mark up tags), are keywords surrounded by angle brackets
How it Began
In 1980, Tim Berners-Lee, a physicist who was a independent contractor at CERN(the European Laboratory for Particle Physics in Geneva, Switzerland), proposed and then made a prototype of ENQUIRE which was a system that researchers at CERN could use in order to use and share documents.
In 1989, Tim Berners-Lee (who was working in a computing services section of CERN), Tim had the idea of enabling researchers from remote sites in the world to organize and put together information. But far from simply making available a large number of research documents as files that could be downloaded to individual computers; he suggested that you could actually link the text in the files themselves. A systems engineer at CERN, Robert Caillian and Tim, submitted separate proposals for an internet based hypertext system providing similar results. The following year they worked together on a joint proposal, the Worldwide Web project which was then accepted by CERN. Tim's prototype Web browser on the NeXT computer came out in 1990.
