Read Unit 1, Lessons 1-3 for next time. Multimedia computing is the combined use of more than one digitized media in an interactive format. Text is a medium. Sound is a medium. Graphics are a medium.
Animation is a medium.
And video is a medium. Texts, sound, graphics, animation, and video are media. In fact, they are the media that are most often meant when we speak of multimedia. Also, although a program with text, sound, graphics, and animation might fit both of the above definitions, video is often considered to be the defining feature of multimedia. Educational applications include encyclopedias, documentaries, CAI, museum kiosks, simulations, and edutainment games.
