--------------------------------------------------------------------------------------------- In this Video Tutorial we will Study and learn the working of Shortest Job First - Non Pre Emptive (SJF). SJF as the name suggests is based on the principle of shortest job first, this essentially means the the process that has the shortest burst time will be processed first. Also this algorithm is Non Preemptive in nature which means that once the CPU starts executing one process it cannot pause or stop it in between and has to completely finish that process before it can move to the next smallest process.
Another variation of SJF is SRT which is shortest remaining time which is SJF with pre-emption.
