What is multimedia computing?

• A sub-set of computing.
• The processes involved in the production of
  applications which achieve their aims through the
  careful combination of different types of media
• DESIGN As with all systems a multimedia system
  must be well designed with a clear aim and a set
  of objectives which will fulfil that aim through
  stated objectives.
• IMPLEMENTATION This involves the use of
  appropriate packages to develop the system.
• EVALUATION All systems require thorough
  evaluation and testing to determine the extent to
  which they work and fullfil the requirements
