CPU Scheduling Algorithm | FCFS (First Come First Serve) – Non Preemptive Explained

In this video, we explain the FCFS (First Come First Serve) CPU Scheduling Algorithm, which is a non-preemptive scheduling technique in Operating Systems. You’ll learn how processes are executed in the order they arrive, and how to calculate key scheduling parameters. ✨ What You’ll Learn: What is CPU scheduling?
