Round Robin Program In C Mcq Exercise 3

• ✅ Behave like First Come First Serve scheduling.
• ✅ More efficient response time for processes.
• ✅ Reduces CPU utilization.

Explanation:

The correct answer is option (b). In case the time quantum is very large, the round-robin scheduling resembles that of the FCFS scheduling because each process continues to run uninterrupted.

1. What should be done to reduce the overhead costs associated with Round Robin Scheduling?

• ✅ By increasing the number of processes.
• ✅ By shortening the time quantum.
• ✅ By increasing the time quantum.
• ✅ Thus, a stack is used instead of a queue.

Explanation:

1. Choose the correct statement for Round Robin scheduling.

• ✅ It is suitable for real-time systems.
• ✅ It assumes correct information regarding the burst time of the processes.
• ✅ It guarantees that none of the processes will starve.
• ✅ It prefers I/O-intensive tasks.

Explanation:

1. Which of the following options is most relevant to Round Robin scheduling and the handling of processes with various burst times but arrive at the same time?

• ✅ The processes with shorter burst times are executed first.
• ✅ The processes with large burst times are executed first.
• ✅ The processes are processed in the order of arrival and have nothing to do with burst time.
• ✅ The priority is given under the burst time.

Explanation:

1. What happens if the time quantum is set to a very high value in a round-robin scheduler?

• ✅ It is like a SJF scheduler.
• ✅ It functions like a First Come First Serve (FCFS) scheduler.
• ✅ Reduces context switching that occurs significantly.
• ✅ Both B and C

Explanation:

1. How can the response time of a process be determined in round-robin scheduling?

• ✅ Arrival time + Burst time
• ✅ The first time it gets the CPU - The arrival time
• ✅ Completion time - Arrival time
• ✅ Time quantum + arrival time

Explanation:

1. In round-robin scheduling, how does the selection of the time quantum influence the turnaround time?

• ✅ A smaller time quantum normally leads to a longer turnaround time.
• ✅ It does not play any role in cutting or reducing the turnaround time.
• ✅ It can be evident that a larger time quantum tends to reduce the turnaround time.
• ✅ generally, a smaller time quantum helps in reducing the turnaround time.

Explanation:

1. What does the word Time Quantum refer to in the Context to Round Robin Scheduling algorithm?

• ✅ The maximum burst time of all processes.
• ✅ The amount of time dedicated to performing processes within the cycle.
• ✅ The average waiting time of processes.
• ✅ The sum of the minimum burst times of all the processes.

Explanation:

The accurate choice is option (b). The time quantum represents the duration allocated for each process to run in its rotation, while the remaining processes are held in a waiting state at the end of the queue.
