Computer
modelling is the representation of three dimensional objects on the computer,
using software designed for the purpose.
Uses of Modelling are:
1. Without
actually creating the system preview of the system is possible.
Example: The
Safety of the car can be tested and previewed during the design.
2. By using
computer model it is easy to predict for the weather forecast.
Example: A
computer model of a weather system can be used to predict storms.
3. Without
putting the people at risk, it is easy to train the people.
Example: For
pilot's training the computer model flight is used.
