In order to improve the system resource utilization rate and reduce the response time, a new task scheduling Priority Backfilling First Come First Serve (PB-FCFS) algorithm has been proposed. This algorithm combines backfilling, FCFS scheduling and adopts the dynamic priority strategy in task ...
In this tutorial, we will learn about the FCFS, i.e. First Come First Serve Scheduling Algorithm with the help of example.

Suppose there are four processes with process ID'sP1,P2,P3, andP4and they enter into the CPU as follows: So, if the OS follows theFCFS algorithm for schedulingthese processes, then they will be executed in the following manner: Gant Chart Explanation As the processes keep arriving, the one...

Round-robin scheduling is a combination algorithm. It uses FCFS scheduling, along with preemption. The processor's service is broken into chunks of time called quantum. These quanta or time slices are then used as the measure for service. Jobs get scheduled in an FCFS fashion as long as ...
In effect, RR scheduling will act as FCFS scheduling. Thus, all the limitations of FCFS will come into the system. If the chosen time quantum is too small, the CPU will be very busy in context switching, i.e. swapping in swapping out processes to and from the CPU and memory. This ...
In FCFS and planning scheduling algorithms, because of the selfishness and exclusiveness of the task's individual scheduling behavior, it is hard to realize a friendly scheduling between two consecutive tasks. This paper gives an online scheduling algorithm based on dynamic planning preemptive threshold...
The proposed genetic algorithm outperforms other task scheduling algorithms such as the classical GA, First Come First Serve (FCFS), and Min-Min algorithms. Alkayal et al. (Alkayal et al., 2016) have used a Multi-objective particle swarm optimization algorithm (MOPSO) based on a new ranking...
