Explanation

FIFO (First-In-First-Out) scheduling is a non-preemptive scheduling algorithm. Once a process starts executing, it runs to completion without being interrupted. The CPU scheduler picks the process at the head of the queue and lets it finish, then moves to the next process. This contrasts with preemptive algorithms like Round Robin that can interrupt running processes.
