Computer simulation

Simulation is a process of forming of a physical model and undergoing experiments on it. This is nothing but a development of a mathematical model and by employing some analytical methods, deriving information from it. In some cases, analytical methods won’t give any result. Then numerical methods or specific algorithms can be employed. The famous definition for simulation was recited by Geoffrey Gordon, a pioneer in simulation. According to him, simulation is the technique of solving problems by observation of the performance, over time, of a dynamic model of the system. The two important components of system simulation are the dynamic model and the time element. If the simulation is carried out within a computer, it is termed as computer simulation. This is widely used when discrete event simulation is required to model the system. Some examples are in manufacturing, commerce, defense and in health. The other name for computer simulation is human out of loop simulation. The architecture computer simulator is software which is used to simulate the computers. This software is divided into two: instruction set simulator and full system simulator.
