First Come First Served (Disk Scheduling)

First Come, First Served (FCFS) is a simple disk scheduling method where the disk requests are handled in the order they arrive. Imagine waiting in line at a checkout: the first person in line is served first, regardless of what they’re buying. Similarly, the disk processes data requests in the sequence they come in, which is easy to implement but can sometimes lead to longer wait times for some requests if earlier requests are large or slow. This method prioritizes fairness but may not be the most efficient in minimizing total wait time.
