Processor Management: This deals with the management of the Central Processing Unit (CPU). The operating system takes care of the allotment of CPU time to different processes. When a process finishes its CPU processing after executing for the allotted time period, this is called scheduling. There is various type of scheduling techniques that are used by the operating systems:#N#Shortest Job First (SJF): The process which needs the shortest CPU time is scheduled first.#N#Round Robin Scheduling: Each process is assigned a fixed CPU execution time in a cyclic way.#N#Priority Based scheduling ( Non-Preemptive): In this scheduling, processes are scheduled according to their priorities, i.e., the highest priority process is scheduled first. If priorities of two processes match, then schedule according to arrival time. 1 Shortest Job First (SJF): The process which needs the shortest CPU time is scheduled first. 2 Round Robin Scheduling: Each process is assigned a fixed CPU execution time in a cyclic way. 3 Priority Based scheduling ( Non-Preemptive): In this scheduling, processes are scheduled according to their priorities, i.e., the highest priority process is scheduled first. If priorities of two processes match, then schedule according to arrival time.
