Question

Which of the following algorithms defines time quantum?
1. shortest job scheduling algorithm
2. round robin scheduling algorithm
3. priority scheduling algorithm
4. multilevel queue scheduling algorithm

Answer 1

Correct Answer - Option 2 : round robin scheduling algorithm

Concept:

Time quantum is defined in round robin scheduling algorithm.

Explanation:

• The period of time for which a process is allowed to run in a pre-emptive multitasking system is generally called the time slice or quantum.
• Each process is assigned a fixed time (Time Quantum/Time Slice) in cyclic way. It is designed especially for the time-sharing system. The ready queue is treated as a circular queue.
• The CPU scheduler goes around the ready queue, allocating the CPU to each process for a time interval of up to 1-time quantum.
• If time quantum for Round Robin scheduling is very large, then it behaves same as FCFS scheduling.
