According to the following table:
Draw a schedule and calulate the sum of completion times if the scheduling
a) First Come First Serve
b) Round Robin with a time slice of 5ms
c) Non-preemptive Shortest Job Next

Transcribed Image Text:### Process Arrival and CPU Time Requirements
The following table illustrates the arrival times and CPU time requirements for a set of processes in a computing environment:
| Process | Arrival Time (ms) | CPU Time Required (ms) |
|---------|-------------------|------------------------|
| P0 | 0 | 60 |
| P1 | 10 | 10 |
| P2 | 20 | 10 |
| P3 | 30 | 10 |
| P4 | 40 | 5 |
| P5 | 50 | 5 |
**Explanation:**
- **Processes (P0 to P5):** These represent distinct tasks or jobs that require processing by the CPU.
- **Arrival Time:** Indicates the time, in milliseconds, at which each process enters the system and is ready for execution.
- **CPU Time Required:** Represents the amount of time, in milliseconds, needed by each process to complete execution on the CPU.
This table provides a foundation for exploring scheduling strategies, such as First-Come, First-Served (FCFS), Shortest Job Next (SJN), or Round Robin, with the goal of optimizing CPU utilization and minimizing waiting and turnaround times.
