What is Multimedia?

Multimedia can have a many definitions these include:

Multimedia means that computer information can be represented through audio, video, and animation in addition to traditional media (i.e., text, graphics drawings, images).
A good general definition is:
Multimedia is the field concerned with the computer-controlled integration of text, graphics, drawings, still and moving images (Video), animation, audio, and any other media where every type of information can be represented, stored, transmitted and processed digitally.
A Multimedia Application is an Application which uses a collection of multiple media sources e.g. text, graphics, images, sound/audio, animation and/or video.

Hypermedia can be considered as one of the multimedia applications.

REFLECTION:
 
               Perhaps the vanguard application of multimedia is virtual reality, a combination of video, stereo, and computer graphics that attempts to create an interactive three-dimensional environment that immerses the user within the simulation. Virtual reality has been employed in a wide range of practical applications: to train military troops, to streamline manufacturing and architectural design processes, to create simulated test environments for industry, and as a form of public entertainment.

One should still keep in mind, however, that even if rendered in a highly advanced multimedia format, an ineffectual presentation is still an ineffectual presentation. One should remain focused on the message being conveyed while shaping the choice and use of materials in accordance with that message.
