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. WebCooperative scheduling of user-level threads. The cooperative model is similar to multiprogramming where a process executes on the CPU until making a I/O request. Cooperative user-level threads execute on the assigned kernel-level thread until they voluntarily give back the kernel thread to the thread manager.
