Question

The quantum time is 2, which means each process is only executing for 2 units of time at a time.

1. Draw three Gantt charts that illustrate the execution of these processes using the following scheduling algorithms: FCFS, Round-Robin, and Preemptive Priority-based scheduling.

2. For each of the scheduling algorithms, compute the waiting times of each process.

3. Compute the average waiting time of each scheduling algorithm.

4. Research and find another scheduling algorithm that has a lower waiting time than these three algorithms.
