It termed as First Come First Serve (FCFS) Scheduling. As its name implies, the process which arrives first in front of CPU for processing, then that process executed first. It is a non-preemptive scheduling algorithm which means in this priority of processing does not matter, i.e., whate...
The FCFS, which stands for First Come First Serve Scheduling Algorithm, is a non-preemptive scheduling algorithm, which means that if a process once starts executing in the processor, then it cannot be preempted in between the processing. Thus, the concept of priority and urgency is not ...
Some of the popular CPU scheduling algorithms are First-Come-First-Served (FCFS), Shortest Job First (SJF), Priority Scheduling and Round Robin (RR). FCFS is the simplest form of CPU scheduling algorithm. This algorithm is simple ... MK Mishra,AK Khan - 《Journal of Global Research in Co...

When P1 is first put in the queue, the wait time is zero and the CPU starts the processing immediately. P2, on the other hand, would have a wait time of 25 seconds. And P3, having arrived last, would have to wait 35 seconds. As a total, an FCFS scheduling algorithm would need 50...
For proper load balancing a new algorithm is developed which use first come first serve and priority scheduling with RBAC An efficient system has three element - collection of device, network connect to these computer and software that enable to share data between these computer. This paper ...
all of the addresses have been specified, the pages which are in use will be printed in order. You will assume an infinite number of frames are available and need not worry about a page replacement algorithm. See section functionality for details. ...
According to the FCFS scheduling algorithm, the process comes the first CPU will execute that process first. So, here CPU will execute process P1. In this schedule, the average waiting time of the system will also be very high. This is because of the convoy effect or starvation. The other...
Average Waiting Time is a standard measure for giving credit to the scheduling algorithm. Several techniques have been applied to maintain the process to make the CPU performance in normal. The objective of this paper is to compare three algorithms, FCFS, SJF, and Round Robin. The target is ...
