Operating System
An operating system is a program that acts as an interface between the computer user and computer hardware, and controls the execution of programs.
CPU Scheduling Algorithm(Preemptive Shortest Job First – SJF)
Shortest Job First (SJF) is a type of disk scheduling algorithm in the operating system in which the processor executes the job first that has the smallest execution time. In the shortest Job First algorithm, the processes are scheduled according to the burst time of these processes.
CPU Scheduling Algorithm(First Come First Serve – FCFS)
First Come, First Served (FCFS) is a type of scheduling algorithm used by operating systems and networks to efficiently and automatically execute queued tasks, processes and requests by the order of their arrival.
