Unformatted text preview: on, storage, representation, manipulation and access of multimedia information. Advances in computer hardware and software have led to the development of inexpensive input, output, storage and processing devices for multimedia computer systems. Technically, multimedia on computer systems is not as new as many people think. For example, computer systems capable of displaying graphs (such as sales graphs), charts (such as bar charts, pie charts), maps (such as contour maps) and engineering drawings (such as mechanical drawings, building plans, circuit diagrams, perspective views) along with text information have been in use for several years. What is more exciting and relatively new about multimedia computer systems is their enhanced capability to handle additional media like sound and video for better information presentation. In general, the data size for multimedia information is much larger than plain text information because representation of graphics, animation, audio or video media in digital form requires much larger number of bits than that required for representation of plain text. Because of this, multimedia computer systems require: 1. Faster CPU (for more quickly processing large amount of data), 2. Larger storage devices (for storing large data files), 3. Larger main memory (for running programs with large data size), 4. Good graphics terminals (for displaying graphics, animation and video), and 5. I/O devices required to play any audio associated with a multimedia application program. Note that logically speaking, all multimedia computer systems need not have all the features listed above. For example, a computer system that does not have the capability to handle audio and video media can still be called a multimedia computer system because it can still handle multiple media (text and graphics). However, a full-fledged multimedia computer system must be capable of handling all types of media discussed above and hen must have all the features listed above.
