Multimedia refers to any combination of text, graphics, audio, animations, and video delivered via computer. It allows for information to be represented through multiple mediums beyond just text. Multimedia can be linear, like movies, or non-linear with user interactivity like games. The main components of multimedia are text, graphics, audio, animations, and video. Multimedia has applications in education for computer-based training, in business for presentations and marketing, and in entertainment with virtual reality and digital kiosks. While it utilizes our natural senses, multimedia also has disadvantages like requiring powerful computers and high development costs. Multimedia authoring tools help create interactive multimedia projects.

retention of facts.
The user can interact.

23. Disadvantages Multimedia
Multimedia requires high-end
computer system.
Sound, images, animation, video
