• Operating systems and networks employ the First Come, First Served (FCFS) scheduling method to efficiently and automatically execute queued tasks, processes, and requests in the order of their arrival. A first-in, first-out (FIFO) or first-come, first-choice (FCFC) scheduling technique is sometimes known as an FCFS scheduling algorithm.
• An FCFS algorithm is predictable due to its simplicity, independent of the tasks or requests it must complete. FCFS algorithms mirror real-life customer service situations, such as grocery store checkout lines, where consumers who arrive first are served first, regardless of the magnitude or complexity of their transaction.
