FCFS磁盘调度算法: 顾名思义,FCFS 调度算法按照请求到达磁盘队列的顺序处理请求。即使更高优先级的请求在计划中稍后到达,FCFS 也会按照它们到达的顺序处理请求,因此我们可以说 FCFS 有一个公平的策略。 例子: 考虑一个有 200 个磁道 (0-199) 的磁盘,磁盘队列具有以下顺序的 I/O 请求:93、176、42、148、21、...

The information stored in persistent cache is not lost after a system restart or virus definitions update. Speed up scanning by reading files in the order they are stored on disk: reduces the amount of time the scan takes to locate stored data by scanning files in the order that their ...
