CPU Scheduling Algorithm | Shortest Job First (SJF) – Non Preemptive Explained

In this video, we explain the Shortest Job First (SJF) CPU Scheduling Algorithm, a non-preemptive scheduling technique in Operating Systems. Learn how the process with the minimum burst time is selected first to reduce waiting time and improve efficiency. ✨ What You’ll Learn: What is SJF scheduling? Why SJF is a non-preemptive algorithm How processes are selected based on burst time Gantt chart construction Calculation of: Completion Time (CT) Turnaround Time (TAT) Waiting Time (WT) Response Time (RT) Advantages and disadvantages of SJF Solved example with step-by-step explanation 🎯 Best for: OS beginners, engineering students, and interview/placement preparation. 👇 Like | Share | Comment your doubts | Subscribe for more OS tutorials! #OperatingSystem #CPUScheduling #SJF #NonPreemptive #OS #GanttChart #TurnaroundTime
