Question

According to the following table:

Draw a schedule and calulate the sum of completion times if the scheduling algorithm used is:

a) First Come First Serve

b) Round Robin with a time slice of 5ms 

c) Non-preemptive Shortest Job Next

### 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.
