Multimedia is defined as computer-based interactive communications that incorporates multiple media like text, graphics, sound, animation and video. It allows for non-linear and interactive experiences where the user determines what content is viewed and when. Hypermedia, the basis for many applications, uses links to allow non-sequential navigation. While multimedia can engage users through multiple senses and allow for individualized learning, it also risks overloading users or losing them without proper structure. Its growth has been driven by decreasing computer costs, more titles, and users' desires for control over their learning experience through different modalities and levels of difficulty. Major categories of multimedia include entertainment, education, corporate communications and reference.
