FCFS Program in CWhat is CPU Scheduling?Processes and activities are scheduled in order to complete the task on time. CPU Scheduling is a method that makes maximum use of the CPU by allowing one process to run while another is delayed (on standby) due to the lack of any resources, such as I/O, etc. CPU scheduling is used to improve the system's effectiveness, speed, and fairness. The operating system must choose one of the processes in the list of ready-to-launch processes whenever the CPU gets idle. A temporary (CPU) scheduler does the selection. The Scheduler chooses one of the ready-to-start memory processes to get the CPU. In this article we are going to talk about FCFS scheduling algorithm The aim is to use the FCFS scheduling algorithm to determine the average waiting time and average turnaround time given n processes and their burst timings. The simplest scheduling technique is first in, first out (FIFO), commonly referred to as first come, first served (FCFS). Processes are merely queued using FIFO in the order that they enter the ready queue. Term used:
In this, the first procedure will be carried out first, and the subsequent process won't begin until the first has been carried out completely. Here, we're assuming that all processes arrive at the same time, or zero. How can I use software to calculate the Round Robin timings below?
Implementation
Program Code: Output: Processes Burst time Waiting time Turn around time 1 10 0 10 2 5 10 15 3 8 15 23 Average waiting time = 8.33333 Average turn around time = 16 ................................................................................................
