Preemptive vs Non-Preemptive Scheduling Explained with Examples | OS | L-9

Preemptive vs Non-Preemptive CPU Scheduling explained clearly for beginners. In this lecture, we explore two fundamental concepts in CPU scheduling used in Operating System — Preemptive Scheduling and Non-Preemptive Scheduling. You will learn how the operating system decides when a running process can be interrupted and when a process must finish execution before another one starts. This lecture explains the core concepts, working mechanisms, execution timelines, advantages, disadvantages, and practical examples of both scheduling approaches. Visual timelines and real-life analogies are used to make the concepts easy to understand.
