Preemptive Scheduling Quiz

What is the main advantage of round-robin scheduling?

• Fair allocation of CPU time

• Faster execution of processes

• Unfair allocation of CPU time

• Increased waiting time for processes

In round-robin scheduling, what happens if a process does not complete within its time quantum?

• The process is moved to the end of the blocked queue

• The process is preempted and placed at the end of the ready queue to wait for its next turn.

• The process is terminated immediately

• The time quantum for the process is increased

What is the time quantum in round-robin scheduling?

• The time quantum is the amount of time each process is allowed to run before being preempted.

• The time quantum is the total time taken for a process to complete

• The time quantum is the number of processes that can run simultaneously

• The time quantum is the amount of time each process is allowed to sleep

What is the drawback of round-robin scheduling?

• Limited number of processes

• Unequal distribution of CPU time

• Inefficient use of CPU time

• Inability to handle priority levels

How is the next process selected in round-robin scheduling?

• Based on the priority of the process

• Randomly selected by the operating system

• Based on a predefined time quantum or time slice

• Based on the amount of CPU time the process has used

What is priority scheduling in operating systems?

• Assigning priority based on the time of arrival

• Executing processes based on their size

• Randomly selecting processes to execute

• Assigning priority to each process based on its importance

What is the main advantage of priority scheduling?

• Better response time for important tasks

• Decreased response time for important tasks

• No impact on task priority

• Increased waiting time for important tasks

What is the main drawback of priority scheduling?

• Fairness

• Efficient

• Starvation

• Low complexity

How is the priority of a process determined in priority scheduling?

• Based on the characteristics of the process

• Alphabetical order

• Randomly selected

• Based on the weather

What is the difference between preemptive and non-preemptive priority scheduling?

• Preemptive priority scheduling allows for task interruptions, while non-preemptive priority scheduling does not.

• Preemptive priority scheduling does not allow for task interruptions, while non-preemptive priority scheduling does.

• Preemptive priority scheduling allows for task completion, while non-preemptive priority scheduling does not.

• Preemptive priority scheduling is slower than non-preemptive priority scheduling.
