Multimedia utilises a combination of different content forms. The term can be used as a noun (a medium with multiple content forms) or as an adjective describing a medium as having multiple content forms. The term is used in contrast to media which only utilise traditional forms of printed or hand-produced text and still graphics. In general, multimedia includes a combination of text, audio, still images, animation, video, as well as forms of interactivity. Multimedia is usually recorded and played, displayed or accessed by information content processing devices, such as computers.
