Ever wondered how your computer, with just one CPU, can seem to run dozens of applications at the same time? The magic behind this multitasking is CPU Scheduling, the operating system's ultimate traffic cop.
In this video, we'll demystify how the OS decides which process gets to use the CPU and when. We'll cover the core goals of scheduling and the fundamental difference between preemptive and non-preemptive approaches. Then, we'll dive into the most famous scheduling algorithms, explaining how each one works with clear examples:
First-Come, First-Served (FCFS)
Shortest Job First (SJF)
Round Robin (RR)
Finally, we'll explore the ultimate trade-off and why there is no single "best" algorithm for every situation. This is a must-watch for any computer science student!
