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 ...
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...
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
Preemptive scheduling like round-robin scheduling can be used to avoid Convoy Effect as in these algorithms every process will be given an equal chance to access the CPU. By using these smaller processes don’t have to wait much for CPU time – making their execution faster and leading to ...
