Detailed explanation-1: -First Come First Serve (FCFS) is an operating system scheduling algorithm that automatically executes queued requests and processes in order of their arrival. It is the easiest and simplest CPU scheduling algorithm.
Detailed explanation-2: -What is FCFS Disk Scheduling Algorithms? FCFS (First-Come, First-Served) Disk Scheduling Algorithm is a simple and easy-to-implement algorithm used in operating systems to manage input/output (I/O) requests from processes to access disk blocks.
Detailed explanation-3: -Priority Based Scheduling Priority scheduling is a non-preemptive algorithm and one of the most common scheduling algorithms in batch systems. Each process is assigned a priority. Process with highest priority is to be executed first and so on. Processes with same priority are executed on first come first served basis.
