Operating System | Unit-2 | Lecture-10 | Round Robin Scheduling Algorithm | Time Quantum | Numerical

In this lecture, we discuss the Round Robin (RR) Scheduling Algorithm, one of the most widely used preemptive CPU scheduling algorithms in Operating Systems. The session explains the concept of Time Quantum (Time Slice) and demonstrates how processes are executed in a cyclic manner through detailed numerical problems. 📌 Topics Covered: Introduction to Round Robin Scheduling Preemptive CPU Scheduling Concept of Time Quantum (Time Slice) Ready Queue Management Context Switching in Round Robin Step-by-Step Numerical Problems Gantt Chart Construction Waiting Time (WT) Calculation Turnaround Time (TAT) Calculation Response Time Analysis Effect of Time Quantum on Performance Advantages and Disadvantages of Round Robin 🎯 Useful for: B.Tech / B.E. CSE & IT Students GATE Computer Science Aspirants University Examination Preparation Competitive Exams and Technical Interviews 📚 Master CPU Scheduling Algorithms through clear explanations, solved examples, and exam-oriented discussions.
