A system requires that arriving processes must wait for service if the needed resource is busy. The system does not use aging to elevate the priorities of waiting processes to prevent indefinite postponement. What other means might the system use to prevent indefinite postponement?

Question

What will be an ideal response?

Answer 1

Simply service requests first-come-first-served. The problem with this is that FCFS can delay more “important” processes while less important processes receive service.
