First-Come, First-Served

First-Come, First-Served (FCFS) is a straightforward scheduling method where processes or tasks are handled in the order they arrive. The system treats each request as it comes, giving priority to the earliest one, without considering their importance or execution time. It's similar to waiting in line at a store: whoever arrives first gets served first. While simple and fair, FCFS can lead to longer wait times for certain tasks if earlier ones take a long time to complete, potentially causing inefficiency and delays.
