Consider three processes P, Q and S. P has a period of 90 ms in which it requires 35 ms of processing. The corresponding values for Q and S are (10, 2) and (30, 5) respectively. Assume that P is the most important process in the system, followed by Q and then S. a. What is the behavior of the scheduler if priority is based on importance? Draw Gantt chart. b. What is the process utilization of P, Q and S. c. How should the process be scheduled so that all deadlines are met. Illustrate your answer using a Gantt chart. Use EDF scheduling
