CPU Scheduling Algorithm | Preemptive Priority Scheduling Explained

In this video, we explain the Preemptive Priority Scheduling Algorithm, an important preemptive CPU scheduling technique in Operating Systems. Learn how the CPU always executes the highest priority process, and how preemption occurs when a new higher priority process arrives. ✨ What You’ll Learn: What is Preemptive Priority Scheduling? How priority-based execution works When and why preemption happens Gantt chart construction with process switching Calculation of: Completion Time (CT) Turnaround Time (TAT) Waiting Time (WT) Response Time (RT) Starvation problem and solution using aging Advantages and disadvantages 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 Operating System tutorials! #OperatingSystem #CPUScheduling #PriorityScheduling #PreemptiveScheduling #OS #GanttChart #Starvation #Aging #CT #TAT #WT #RT
