Problem: In a certain computer system, five (5) processes A, B, C, D, and E are active with their burst times (in ms) of 8, 10, 2, 4, and 3 respectively. These processes come at times (in ms.) 16, 0, 4, 20, and 29 respectively and use FCFS to schedule the execution.  Required information: Draw the Gantt chart showing the execution of the CPU. What is the CPU utilization? What is the system’s throughput (in process /ms)?
