2. Topic 6: CPU Scheduling is talking about various scheduling algorithms. Following is information we have about the processes that ask to run on the CPU: 2 of 17 112022 CISC 3320 TR8 Final CUNY Brooklyn College Suppose that the operating system uses exactly one of the following five scheduling algorithms that we covered in class to schedule the execution of processes on the CPU: FIFO, Non-preemptive SJF, Priority, and Round-Robin. Below is the Gantt chart that results from using the algorithm: Which one algorithm does the operating system use? Explain your answer based on the Gantt chart. If you conclude that the used algorithm is Round-Robin, also indicate the time slice that the operating system uses. In case the Gantt chart matches more than one possible algorithm, provide your explanation for only one of these algorithms. (Slides: Topic 6, slides 1226.
