Priority Scheduling Algorithm || Preemptive || Example 3 || Operating System
In this video, we explain the Priority Scheduling Algorithm in Operating Systems with clear concepts and solved examples.
Priority Scheduling is a CPU scheduling algorithm where each process is assigned a priority, and the CPU is allocated to the process with the highest priority. It can be implemented in both preemptive and non-preemptive forms and is widely used in real operating systems.
📘 Topics Covered:
✅ What is Priority Scheduling in OS?
✅ Preemptive vs Non-Preemptive Priority Scheduling
✅ How priority scheduling works
✅ Solved numerical example
✅ Gantt Chart construction
✅ Calculation of Waiting Time
✅ Calculation of Turnaround Time
✅ Problem of Starvation
✅ Solution using Aging
✅ Advantages and Disadvantages
✅ Important points for GATE CS & university exams
This lecture is extremely useful for B.Tech / BCA / MCA students, GATE aspirants, and anyone preparing CPU scheduling numericals and OS interviews.
👉 Watch till the end to fully master Priority Scheduling problems, which frequently appear in GATE, semester exams, and placements.
