Operating Systems Quiz

What is the primary function of a CPU scheduler?

• To manage I/O devices

• To choose which process to run first

• To allocate memory

• To terminate processes

Which of the following is a preemptive scheduling algorithm?

• First Come First Serve (FCFS)

• Shortest Job First (SJF)

• Priority Scheduling

• Round Robin (RR)

What does non-preemptive scheduling mean?

• Processes can be interrupted at any time

• Processes run until completion or voluntarily yield CPU

• Processes are scheduled based on priority

• Processes are executed in a round-robin manner

What is the aim of CPU scheduling?

• To increase I/O operations

• To ensure CPU is idle

• To minimize memory usage

• To maximize CPU utilization

Which of the following terms refers to the time taken from submission to completion of a job?

• Throughput

• Response time

• Turnaround time

• Waiting time

What is the time quantum in a Round Robin scheduling algorithm?

• The average time for all processes

• The maximum time a process can run before being preempted

• The time taken to switch processes

• The total time a process runs

In which scheduling algorithm do processes move between queues?

• First Come First Serve

• Multilevel Feedback Queue

• Multilevel Queue

• Round Robin

What is the main disadvantage of a very short time quantum in Round Robin scheduling?

• Increased process switching time

• Reduced context switching

• Decreased response time

• Increased CPU efficiency

Which of the following is NOT a criterion for CPU scheduling?

• Response time

• Memory allocation

• Efficiency

• Fairness

What is the purpose of a Gantt Chart in CPU scheduling?

• To calculate memory usage

• To manage user interfaces

• To visualize process execution

• To determine I/O operations
