How do different scheduling algorithms compare in terms of performance?

Different scheduling algorithms, like FCFS, SJF, and Round Robin, have varying performance metrics such as turnaround time, waiting time, and CPU utilization. Would you like a detailed comparison of specific algorithms?

Yes, can you compare FCFS and SJF in terms of turnaround time?

Sure! FCFS (First-Come, First-Served) can lead to longer turnaround times, especially if a long process is at the front of the queue. In contrast, SJF (Shortest Job First) minimizes turnaround time by prioritizing shorter processes. Would you like to see an example with specific numbers?

That would be great! Can you provide an example?

Absolutely! Let's say we have three processes with the following burst times: P1 = 8, P2 = 4, P3 = 2. In FCFS, the turnaround times would be 14, 10, and 2 respectively. In SJF, the turnaround times would be 8, 4, and 0. This shows SJF significantly reduces turnaround time.

Thanks! What about Round Robin? How does it compare?

Round Robin can provide a fairer distribution of CPU time among processes, but its performance can vary based on the time quantum. It may lead to higher turnaround times compared to SJF, especially with a small time quantum. Would you like to explore more about time quantum effects?
