HTML stands for Hyper Text Markup Language, which is the most widely used language on Web to develop web pages. Hypertext systems were envisioned as early as 1940 by Vannevar Bush and have a rich history. Tim Berners-Lee and Robert Caillau at CERN, in 1989-1990 developed HTML as a simplification of SGML. CERN launched the web in 1991 (HTML+HTTP).
Hypertext Markup Language is the underlying markup language of the World Wide Web. It’s the common thread that ties together virtually every Web site, from large-scale corporate sites such as Microsoft’s to single-page classroom projects at the local grade school.
Hypertext refers to the way in which Web pages (HTML documents) are linked together. Thus, the link available on a webpage is called Hypertext. A markup language annotates or “marks up” plain text, letting a browser knows how to format that text so it looks good on a Web page.
As its name suggests, HTML is a Markup Language which means the user can use HTML to simply "mark-up" a text document with tags that tell a Web browser how to structure it to display.
The HTML page is actually stored on the computer that is hosting the web site and the page is sent to the user browser.
