Round Robin Program In C Mcq Exercise 1

• ✅ Queue
• ✅ Linked List
• ✅ Tree

Explanation:

The correct answer is option (b). Queue data structure is used in the Robin scheduling process.

1. Which of the following is a parameter for round-robin scheduling?

• ✅ Burst time
• ✅ Arrival time
• ✅ Time quantum
• ✅ Priority

Explanation:

The correct answer is option (c). The time quantum or time slice is the strategic factor that determines the amount of time that a process is to be allowed before another process takes over.

1. In Round Robin scheduling, what happens if a process does not complete its time slot (known as a quantum)?

• ✅ It is terminated
• ✅ It is added at the end of the sending queue
• ✅ It is given immediate extra time
• ✅ Depending on the situation, it is relocated to a higher-priority work category.

Explanation:

The correct answer is option (b). If a process does not get an opportunity to complete its cycle within the shareholders' time quantum, it will have to wait at the end of the line for the next round.

1. How does the round-robin schedule's time quantum determine the algorithm's efficiency?

• ✅ Larger time quantum increases context switches
• ✅ Smaller time quantum increases CPU utilization
• ✅ Larger time quantum reduces context switches
• ✅ Smaller time quantum decreases throughput

Explanation:

The accurate choice is alternative (c). A significant time quantum aids in reducing the number of context switches. Small tasks might experience delays in response times. Round Robin scheduling faces increased overhead during process switches. Nonetheless, a longer time quantum guarantees that lengthy processes receive necessary resources by reducing the frequency of context switches.

1. Let's examine the code snippet below:
Example
Copy
where remaining_time is greater than 0.
if (remaining_time <= time_quantum) {
run_process(process);
remaining_time = 0;
} else {
run_process_for_quantum(process, time_quantum);
remaining_time -= time_quantum;
enqueue(process);
}
}
Try it Yourself

This code depicts what?

• ✅ Priority Scheduling
• ✅ Round Robin Scheduling
• ✅ Shortest Job First Scheduling
• ✅ First In First Out planning

Explanation:

The accurate choice is (b). The provided code demonstrates Round-Robin scheduling, in which a process is allocated the CPU for a specific time slice and is placed in a queue if additional time is left.
