1. How does a simulation of the simple process model help you understand the dynamic behavior of the simple batch operating system? Explain.
2. Comparing two models with different processor speeds—one with a slow service rate and the other with a very fast rate—can be simulated by changing the workload and providing two different values for the average service time demands of the processes. Change the simulation model of the simple process model to replace the processor with a faster one. How much faster is the new processor? Change the program and run several simulations. Explain the change in the performance metrics.
3. Add more memory to the simulation model (i.e., increase the memory capacity of the model). Run the simulation several times. Give your conclusions.
