What is fcfs mean?

FCFS (First-Come, First-Served) is a scheduling algorithm used in computer operating systems and data processing systems. In this algorithm, tasks are executed in the order they arrive, with the first task to arrive being the first one to be executed.

One advantage of FCFS is that it is easy to implement and understand, making it a popular choice for simple systems. However, one drawback is that it can lead to longer waiting times for tasks further down the queue, causing potential performance issues in certain situations.

Overall, FCFS scheduling is a simple and fair algorithm, but may not always be the most efficient or optimal choice depending on the specific system and workload.
