Multimedia is the integration of multiple forms of media. This includes text, graphics, audio, video, etc. For example, a
presentation involving audio and video clips would be considered a “multimedia presentation.” Educational software that
involves animations, sound, and text is called “multimedia software.” CDs and DVDs are often considered to be
“multimedia formats” since they can store a lot of data and most forms of multimedia require a lot of disk space.
Webcam incorporates both audio and video. Similarly, microphone is a multimedia device because it incorporates sound

require input from the user to function properly.
