Question
### Process Scheduling Example Assume that you have processes as detailed in the table below: | No | Process | Time Arrival | Time Execution | Priority | |----|---------|--------------|----------------|----------| | 1 | P1 | 10 | 10 | 1 | | 2 | P2 | 5 | 5 | 2 | | 3 | P3 | 0 | 15 | 3 | | 4 | P4 | 3 | 10 | 3 | | 5 | P5 | 15 | 20 | 4 | **Task:** Please draw the timeline for these processes using Priority-driven scheduling. **Explanation:** - **Priority-driven Scheduling:** In this scheduling method, the process with the highest priority (lowest numerical value) is executed first. If two processes have the same priority, they are scheduled based on their arrival time. **Processes Details:** - **P1**: Arrives at time `10`, requires `10` units of execution time, has the highest priority `1`. - **P2**: Arrives at time `5`, requires `5` units of execution time, has priority `2`. - **P3**: Arrives at time `0`, requires `15` units of execution time, has priority `3`. - **P4**: Arrives at time `3`, requires `10` units of execution time, has priority `3`. - **P5**: Arrives at time `15`, requires `20` units of execution time, has the lowest priority `4`. **Next Steps:** 1. List the processes in order of their priority. 2. If two processes have the same priority, list them based on their arrival time. 3. Draw the timeline reflecting the order of execution according to the priority and arrival times.
