 Definition of Multimedia


  Multimedia is any combination of
text, art, sound, animation, and video

      other electronic or digitally
           manipulated means.
   Introduction to Multimedia
• Multimedia becomes interactive multimedia
  when a user is given the option of
  controlling the elements.

• Interactive multimedia is called hypermedia
  when a user is provided a structure of
  linked elements for navigation.
   Introduction to Multimedia
• A multimedia project development requires
  creative, technical, organizational, and
  business skills.

• Multimedia developers develop multimedia
  projects.
    Introduction to Multimedia
• Multimedia projects can be linear or
  nonlinear.

• Projects that are not interactive are called
  linear.

• Projects where users are given navigational
  control are called non-linear and user-
  interactive.
 4 Characteristics of Multimedia
