Preemptive vs non-preemptive scheduling

How does preemptive scheduling affect the waiting time of processes?

a: It increases the waiting time due to context switching Explanation

Explanation

b: It decreases the waiting time by allowing higher-priority processes to execute first Explanation

Explanation

c: It does not affect the waiting time Explanation

Explanation

d: It causes no effect on the process execution order Explanation

Explanation

Which of the following is an advantage of non-preemptive scheduling?

a: Lower waiting times Explanation

Explanation

b: Reduced context switching overhead Explanation

Explanation

c: Higher throughput Explanation

Explanation

d: Faster response time Explanation

Explanation

Which scheduling type is more likely to lead to starvation of lower-priority processes?

a: Round-robin Explanation

Explanation

b: Preemptive scheduling Explanation

Explanation

c: Non-preemptive scheduling Explanation

Explanation

d: First-come, first-served Explanation

Explanation

Which of the following factors affects the performance of preemptive scheduling?

a: Time slice length Explanation

Explanation

b: Number of processes in the queue Explanation

Explanation

c: Priority of processes Explanation

Explanation

d: Amount of available memory Explanation

Explanation

In a non-preemptive scheduling system, how does the system handle a newly arrived process?

a: It immediately interrupts the current process to start the new one Explanation

Explanation

b: It waits until the current process finishes before starting the new one Explanation

Explanation

c: It assigns a priority to the new process and waits for the next time slice Explanation

Explanation

d: It executes the new process in parallel with the current one Explanation

Explanation

Which factor is least affected by the choice of scheduling method?

a: Turnaround time Explanation

Explanation

b: Context switching time Explanation

Explanation

c: CPU utilization Explanation

Explanation

d: Response time Explanation

Explanation

What is the main cause of higher context switching overhead in preemptive scheduling?

a: Frequent process interruptions Explanation

Explanation

b: Low process priority Explanation

Explanation

c: Long time slice duration Explanation

Explanation

d: Excessive CPU utilization Explanation

Explanation

How does the non-preemptive scheduling method affect system responsiveness?

a: It improves system responsiveness by quickly switching between tasks Explanation

Explanation

b: It degrades system responsiveness as a process must complete before another can start Explanation

Explanation

c: It does not affect system responsiveness Explanation

Explanation

d: It leads to faster execution of critical processes Explanation

Explanation

Which scheduling algorithm is more likely to maximize CPU utilization?

a: Preemptive scheduling Explanation

Explanation

b: Non-preemptive scheduling Explanation

Explanation

c: Round-robin Explanation

Explanation

d: First-come, first-served Explanation

Explanation

In a preemptive scheduling system, what happens when a process runs out of its time slice?

a: The process is removed from the queue Explanation

Explanation

b: The process is paused and added back to the ready queue Explanation

Explanation

c: The process is completed and removed from the system Explanation

Explanation

d: The process is immediately restarted from the beginning Explanation
