WebFeb 24, 2024 · First come first serve scheduling algorithm states that the process that requests the CPU first is allocated the CPU first and is implemented by using FIFO queue. Characteristics of FCFS: FCFS supports non-preemptive and preemptive CPU scheduling algorithms. Tasks are always executed on a First-come, First-serve concept. WebApr 2, 2024 · First come, first served First in, first out (FIFO), also known as first come, first served (FCFS), is the simplest scheduling algorithm. FIFO simply queues processes in the order that they arrive in the ready queue. This is commonly used for a task queue, for example as illustrated in this section.
