a. A fast-food restaurant has four kinds of employees: (a) order takers, who take customers' orders; (b) cooks, who prepare the food; (c) packaging specialists, who stuff the food into bags; and (d) cashiers, who give the bags to customers and take their money. Each employee can be regarded as a communicating sequential process. What form of interprocess communication do they use? Relate this model to processes in UNIX. b) Five jobs are waiting to be run. Their expected run times are 9, 6, 3, 5, and x. In what order should they be run to minimize average response time? (Your answer will depend on x). c) The aging algorithm with a = 1/2 is being used to predict run times. The previous four runs, from oldest to most recent, are 40, 20, 40, and 15 msec. What is the prediction of the next time? Explain.
