Step 1 Introduction
Operating system algorithms which are algorithms that are used to manage processes within a computer system. Common algorithms include First Come First Serve (FCFS), Shortest Job Next (SJN), Priority Based Scheduling , Shortest Remaining Time, Round Robin, Earliest Deadline First (EDF), and Multilevel Queue Scheduling. Each of these algorithms which has its own benefits and drawbacks, and is best suited for a certain type of operating system or process.
