2. Suppose we have three processes.
| Process ID | Required CPU time | Arrival Time |
| A | 200 msec | 50 msec |
| B | 400 msec | 150 msec |
| C | 300 msec | 0 msec |
- Draw the execution timeline for the FIFO scheduling policy, and compute the average response time, average wait time, and average turnaround time. Please show your work.
- Assume the time slice of 100 msec and a zero context-switching cost. Draw the execution timeline for the round-robin scheduling policy, and compute the average response time, average wait time, and average turnaround time. Please show your work.
- Draw the execution timeline for the SJF scheduling policy, and compute the average response time, average wait time, and average turnaround time. Please show your work.
- Draw the execution timeline for the SRTF scheduling policy, and compute the average response time, average wait time, and average turnaround time. Please show your work.
