Computer simulation involves using a computer program to imitate reality. It allows for realistic situations to be portrayed in a cost-effective way that provides immediate feedback and involves students without risk. However, computer simulations can be costly to develop and maintain, and they limit the number of people who can access the learning at the same time.

1. computer simulation
computer simulation - (computer science)
the technique of representing the real
world by a computer program
A computer simulation is an imitation of
reality.

2. ADVANTAGES OF computer SIMULATION
 Can portray realistic situations
 Motivating leaners by making learning fun and interactive
 Critical situations can be investigated without risk.
 It is cost effective.
 immediate feedback
 Students involved
 Make the impossible possible
 Save the money and other resources
 Allow repetition

3. Disadvantages
 Can be costly to buy and maintain
computerized simulators
 Limits number of people who can access
the learning at the same time
