Consider there are two set of processes Set1 has processes with longer burst times than Set2. The operating system is implementing Shortest Job First (SJF) for Scheduling. Which SJF approach is suitable for Set1 and Set2 (choose from Preemptive and Non-Preemptive). Justify your answer. If OS claims provision of protection and sharing mechanisms at the same time, do these mechanisms not violate the purpose of each other? Justify. How does disk-based queuing effect OS queue order efforts?
