MIME (Multi-Purpose Internet Mail Extensions) is an extension of the original Internet e-mail protocol that lets people use the protocol to exchange different kinds of data files on the Internet: audio, video, images, application programs, and other kinds, as well as the ASCII text handled in the original protocol, the Simple Mail Transport Protocol (SMTP). In 1991, Nathan Borenstein of Bellcore proposed to the IETF that SMTP be extended so that Internet (but mainly Web) clients and servers could recognize and handle other kinds of data than ASCII text. As a result, new file types were added to "mail" as a supported Internet Protocol file type.
MIME types tell browsers how to handle specific extensions. For example, the text/html MIME type equates to .htm, .html, and .shtml extensions on most servers, and this tells your browser to interpret all files with those extensions as HTML files. You can alter or add new MIME types specifically for your site (note that you can not alter the system defined MIME type values). MIME types are often used to handle new technologies as they appear. When WAP technology first appeared no one had these extensions set up on their server. With MIME types, however, you could have set it up yourself and begun serving WAP pages immediately.
