操作系统FCFS调度 先来先服务(FCFS)调度算法根据其到达时间简单地调度作业。 就绪队列中第一个工作将首先获得CPU。 工作到达时间越少,工作得到的CPU就越快。 如果第一个进程的突发时间是所有作业中最长的,则FCFS调度可能会导致饥饿问题。 FCFS的优势 简单 容易 先到先得 FCFS的缺点 调度方法是非抢先式的,该进程将运
In this tutorial, we will learn about the FCFS, i.e. First Come First Serve Scheduling Algorithm with the help of example. By Monika Sharma Last updated : May 06, 2023 What is First Come First Serve Scheduling (FCFS) Algorithm?
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 proc
In FCFS scheduling the burst time of the first job is the highest among all the other jobs so this situation is referred to as a convoy effect.For example, there is one CPU intensive process (which has large burst time) in the ready queue, and many more other processes comparatively ...
