Web2) Shortest–Job–First Scheduling : SJF is a preemptive and Non-Preemptive algorithm. It based on length of latter’s next CPU burst. If a process acquired CPU and execution is going on, a new process with small CPU burst entered. Then CPU is preempted from current process and will give to further process.
