Scheduling — Quiz

Test your understanding of scheduling with 5 practice questions.

Practice Questions

Question 1

Which scheduling disorder is characterized by a lower‐priority task holding a resource needed by a higher‐priority task, causing the latter to wait indefinitely?

Question 2

Given three processes arriving at time 0 with parameters: P₁(burst=4, priority=2), P₂(arrival=1, burst=3, priority=1), P₃(arrival=2, burst=2, priority=3), what is the average turnaround time under preemptive priority scheduling (lower number= higher priority)?

Question 3

What is a primary advantage of multi‐level feedback queue scheduling compared to single‐level priority scheduling?

Question 4

If context switch overhead is $0.2\,$ms and the time quantum is $2\,$ms in Round Robin, what is the CPU utilization assuming continuous ready processes?

Question 5

In Round Robin with quantum $4\,$ms for processes P₁=10\,ms, P₂=4\,ms, P₃=6\,ms (all arrive at 0), what is the average turnaround time?
