Multimedia :
Multimedia is media and content that uses 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 use traditional forms of printed or hand – produced material. Multimedia includes a combination of text, audio, still images, animation, video, and interactivity content forms.
Hypermedia:
Hypermedia is not constrained to be text – based. It can include other media, e.g., graphics, images, and especially the continuous media — sound and video. Apparently, Ted Nelson was also the first to use this term. Hypermedia can be considered as one of the multimedia applications.
