First-Come, First-Served (FCFS)

First-Come, First-Served (FCFS) is a basic approach to handling processes or requests where those that arrive first are addressed first. Imagine waiting in a queue at a coffee shop: the first person in line gets their order fulfilled before anyone else. In various contexts, such as scheduling tasks in computers or managing customer service, FCFS is straightforward and fair, but it can lead to inefficiencies, as longer tasks may delay the completion of shorter ones. Overall, FCFS operates on the simple principle of prioritizing the order of arrival.
