__Modeling and Simulation: By //Yazan Hamadeh//__

__Overview:__  A computer simulation, or a computer model is a computer program, or network of computers, that recreates the conditions and models it into a realistic virtual version of the real subject or experience. Simulations can be used to explore and gain new insights into new technology, and to estimate the performance of systems too complex for analytical solution. It is used in sciences, sports, engineering, health and medicine etc.  **__Interesting Videos __**

__Advantages:__ 
 * Computer simulation offers the opportunity to experiment with different scenarios and events, which for a number of reasons, cannot normally be experimented with in the traditional way.(i.e. too long to set up, costs, weather conditions, regulations)
 * Computer simulation offers you the ability to repeat experiments numerous amounts of times, which is not possible in real life, saving time, costs, labor and human efforts in the long term.
 * Gives the user a chance to learn before operating in the real situation, so errors made in the learning process can be made in the simulator not in a real life situation.
 * The simulator is operating in a safe environment compared to the real life situation.The process to be examined can proceed too slowly in reality, e.g. biological growing processes.

__Disadvantages:__


 * A computer simulation program cannot develop the students' emotional and intuitive awareness, a real life experiment is needed
 * Simulations are becoming more and more realistic, but are still far from being close to experiencing the real thing
 * Can be too expensive up front (short term)
 * Some people like traditional method s
