采用最短作业优先的抢先调度算法(Preemptive SJF)调度表2-7所示的进程,平均等待时间为 (6) 。 A.2.0B.2.4C.2.8D.3.0 相关知识点: 试题来源: 解析 C [分析] 由于采用的是最短作业优先的抢先调度算法,所以在最开始的时候,P1进程运行。在P1运行两个小时后,P2到达,P2运行的时间比P1小,所以P2运行。P2运行两...
TheShortest Job Scheduling Algorithmkeeps track of the Burst time of all the available processes and then assigns the processor to that process which has the shortest burst time. This is also a type of non-preemptive scheduling algorithm where once a process starts its execution, it cannot be ...

In this method, burst time can be predicted according to the type of process, User Process The Process which is initiated by the users is referred to as user processes. User processes can be of the following types. Foreground Process
