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
What is First Come First Serve Scheduling (FCFS) Algorithm?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 processin...
How to Avoid Convoy Effect in FCFS Scheduling?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 –...
C. RRD. Priority Scheduling 相关知识点: 试题来源: 解析 D 在操作系统中,题目要求的调度算法是根据优先级分配CPU时间,对各选项逐一分析如下: - **A. FCFS(先来先服务)**:按进程到达顺序分配CPU时间,不涉及优先级。排除。 - **B. SJF(最短作业优先)**:基于进程预计执行时间(短作业优先),优先级由...
B: 3ms (CPU), 8ms (I/O), 7ms (CPU) C: 2ms (CPU), 1ms(I/O), 4ms (CPU), 1ms (I/O), 3ms (CPU) Calculate the turnaround (completion) and wait times of all processes and the average of these times using each of the following scheduling algorithms: ...
if the CPU is idle then create a new event PROCESS_STARTS event for this process at t = currentTime else put the process in the CPU event with priority as follows: if schedulerType is FCFS or RR then priority = 0 else if schedulerType is SJF then ...
