It was mentioned in the beginning of this chapter that the capability of computers
to handle different types of media makes them suitable for a very wide range of
applications and users. Below we discuss some of the most commonly known
applications of multimedia. Please note that there are many more multimedia
applications in addition to those discussed here and it is not possible to cover all of
them. The basic idea here is to introduce the readers to some key multimedia
applications so that they can gain sufficient background to appreciate the use of
multimedia and to visualize its other applications. For ease of presentation, the
applications discussed below have been grouped in areas.
