WebBy Dinesh Thakur. Definition: Round robin scheduling is the preemptive scheduling in which every process get executed in a cyclic way, i.e. in this a particular time slice is allotted to each process which is known as time quantum. Every process, which is present in the queue for processing, CPU is assigned to that process for that time quantum. This type of multitasking is called cooperative because all programs must cooperate for the scheduling scheme to work.
