To have the world be integrated   Martin Luther King Jr. had a dream that everyone would be free and have equal rights and that one day people of different races wouâ¦ld all be holding hands and walking side by side.
Simulation is the imitation of the operation of a real-world process or system over time. The act of simulating something first requires that a model be developed; this model represents the key characteristics or behaviors/ functions of the selected physical or abstract system or process.
Time is continuous, as in the real world. Another example of live simulation is testing a car battery using an electrical tester. Virtual simulations typically involve humans and/or equipment in a computer-controlled setting. Time is in discrete steps, allowing users to concentrate on the important stuff, so to speak.
