技术标签:OS 1,FCFS 先服务先调度 FCFS策略可以通过FIFO队列容易的实现。当一个进程进入就绪队列时,它的PCB会被连接到队列尾部。当CPU空闲时,它会分配给位于队列头部的进程,并且这个运行进程从队列中移去。 缺点:平均等待时间往往很长。 假设有这么三个进程P1,P2,P3按顺序到达,并且按FCFS顺序进行处理 进程 执行时...

first in first out. We can also write C/C++ program for first come first serve scheduling algorithm. Example: real-life example of FCFS is buying a ticket on the ticket counter. In this, a person is served according to queue manner. The man who arrives first in the queue first buys ...

So, if the OS follows the FCFS algorithm for scheduling these processes, then they will be executed in the following manner:Gant ChartTotal Turn around Time = 5 + 6 + 4 + 6 = 21 milliseconds Average Turn Around Time= Total Turn Around Time / Total No. of Processes = 21 / 4 = ...
El**私奔上传465KB文件格式zip 操作系统上机实验,要求使用C语言实现FCFS/SSTF/SCAN/CSCAN四种磁盘调度算法 本程序界面清晰,运行结果与教材一致,可以修改最大磁道号和初始磁道号(SSTF,SCAN,CSCAN算法中从哪个磁道号开始搜索),交互性较好 欢迎大家下载参考
