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.

Which algorithm works on the bases of time quantum?

RR Scheduling algorithm is work based on fixed time quantum. Most modern systems use time quantum between 10 and 100 milliseconds, and context switch times on the order of 10 microseconds. The major problem in RR scheduling is that how the time quantum is fixed for all the process.

What is a time quantum?

A chronon is a proposed quantum of time, that is, a discrete and indivisible "unit" of time as part of a hypothesis that proposes that time is not continuous.
