HTML
Hypertext markup language or html is a set of tags and rules (conforming to and a subset of SGML) for using them in developing hypertext documents [1]. It is a formatting and markup language used to make hypertext documents for use on the Web. HTML resembles old-fashioned typesetting code or the Standard Generalized Markup Language, where a block of text is surrounded by tags that indicate how it should appear. HTML allows text to be linked to another file on the Internet similar in practice to Vannevar Bush's proposed Memory Extender or Memex for short. HTML is a W3C standard used for creating World Wide Web pages.
Tim Berners-Lee created the original HTML (and many associated protocols such as HTTP) on a NeXTcube workstation using the NeXTSTEP development environment.
