Operating Systems- CPU Scheduling - Shortest Job First Algorithm (SJF) - Non-Preemptive

In this video, we’ll explore Shortest Job First (SJF) scheduling, a widely studied CPU scheduling algorithm known for its optimality under certain conditions. We’ll break down the non-preemptive SJF, where the CPU completes the current job before switching to a new one.

Through step-by-step examples and clear explanations, we’ll illustrate how SJF minimizes average waiting time and how it compares to other scheduling techniques. By the end of this video, you’ll be able to solve scheduling problems, calculate key performance metrics like turnaround time, and understand when and why you might choose SJF for process management.
