4. USES of MULTIMEDIA
 EDUCATION- Multimedia is use to create and produce computer-based training (CBT) materials
and courses , including online and CD based encyclopedias. It has been observed that learning is
faster and easier with a properly assembled multimedia of voice , video, graphics, and texts.

disease to human body to clearly find and develop ways of preventing them.

5.  Mathematics and Scientific Research – Multimedia issued to simulate and model various
situations that would otherwise be difficult to grasp in real time, as in the case of an erupting
volcano or tornado, wherein after effects can be presented to colleagues or to the learning
public. Mathematical equations and formulas that can be represented as visual models can
easily be viewed by the use of multimedia. Chemical and molecular models can be also use
