FCFS Scheduling, or First-Come, First-Served Scheduling, is a simple method used in operating systems to manage processes. In this approach, the process that arrives first in the queue is the one that gets executed first. This method is straightforward and easy to implement, making it a popular choice for basic scheduling needs. However, FCFS Scheduling can lead to inefficiencies, particularly with longer processes. If a long process is at the front of the queue, it can delay all subsequent processes, leading to increased wait times. This phenomenon is known as the "convoy effect," which can negatively impact overall system performance.
