Operating System Scheduling Algorithms Quiz

What is the main characteristic of First-Come-First-Served (FCFS) Scheduling?

• Processes can move between queues

• Oldest process in the Ready queue is selected

• Shortest expected processing time

• Preemption based on a clock

What is the main feature of Round-Robin Scheduling?

• Preemption based on a clock

• An amount of time is determined for each process

• Shortest expected processing time

• Processes can move between queues

Which scheduling algorithm is also known as Shortest Job Next (SJN)?

What is the preemptive version of the shortest process next policy?

Which scheduling algorithm accounts for the age of the process?

• Multilevel Queue Scheduling

• Shortest Process Next (SPN)

• Highest Response Ratio Next (HRRN)

• Round-Robin Scheduling

When is Multilevel Queue Scheduling based on fixed priority used?

• When processes are easily classified into different groups

• When processes can move between queues

• When the currently running process is placed in the ready queue

• When an amount of time is determined for each process
