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
I/O devices required to play any audio associated with a multimedia
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.
