Differences Between Preemptive and Non-Preemptive Scheduling: Parameter PREEMPTIVE SCHEDULING NON-PREEMPTIVE SCHEDULING Basic In this resources(CPU Cycle) are allocated to a process for a limited time. Once resources(CPU Cycle) are allocated to a process, the process holds it till it completes its burst time or switches to waiting state. Interrupt Process can be interrupted in between. Process can not be interrupted until it terminates itself or its time is up. Starvation If a process having high priority frequently arrives in the ready queue, a low priority process may starve. If a process with a long burst time is running CPU, then later coming process with less CPU burst time may starve. Overhead It has overheads of scheduling the processes. It does not have overheads. Flexibility flexible rigid Cost cost associated no cost associated CPU Utilization In preemptive scheduling, CPU utilization is high. It is low in non preemptive scheduling. Examples Examples of preemptive scheduling are Round Robin and Shortest Remaining Time First. Examples of non-preemptive scheduling are First Come First Serve and Shortest Job First.
