Web3. Medium-Term Scheduler. The switched-out processes are handled by the Medium-Term scheduler. If the running state processes require some IO time to complete, the state must be changed from running to waiting. This is accomplished using a Medium-Term scheduler. It stops the process from executing in order to make space for other processes. WebRound Robin Scheduling. Round robin is a scheduling algorithm where a fixed amount of time is chosen and assigned to each process. The scheduler then cycles through all of these processes until they are all completed. Processes that do not finish during their assigned time are rescheduled to allow all other processes an opportunity to run first.
WebSchedulers. A process migrates among the various scheduling queues throughout its lifetime. The OS must select, for scheduling purposes, processes from these queues in some fashion. The selection process is carried out by the appropriate scheduler . Often, in a batch system, more processes are submitted than can be executed immediately.
