SGML
SGML (Standard Generalized Markup Language) is a system for organizing and tagging elements of a document. SGML was developed and standardized by the International Organization for Standards (ISO) in 1986. SGML itself does not specify any particular formatting; rather, it specifies the rules for tagging elements. SGML itself is not a markup language; rather, it is a language to create markup languages. Because of SGML's complexity, HTML and XML were developed as simplified subsets of SGML for use on the Internet. SGML does not specify any particular formatting; rather, it specifies the rules for tagging elements. These tags can then be interpreted to format elements in different ways.
XML
XML is a lightweight version of SGML which keeps enough of its functionality to make it useful but removes all the optional features which made SGML too complex to program for in a web environment. XML is the Extensible (not a fixed format) Markup Language, instead XML is a meta-language, a language for describing other languages. It improves the functionality of the Web by letting you identify your information in a more accurate, flexible, and adaptable way.
HTML
HTML (Hypertext Markup Language) is a computer language devised to allow website creation. It is the set of markup symbols or codes inserted in a file intended for display on a World Wide Web browser page. Markup is what HTML tags do to the text inside them. They mark it as a certain type of text (italicised text, for example). The markup tells the Web browser how to display a Web page's words and images for the user, while also
