此为操作系统实验报告： scan,cscan算法模拟磁盘调度 内含：程序流程图 设计思路 主要源码等等。 简介：磁盘是一种高速、大容量、旋转型、可直接存取的存储设备。它作为计算机系统的辅助存储器，担负着繁重的输入输出任务、在多道程序设计系统中，往往同时会有若干个要求访问磁盘的输入输出请求等待处理。系统可采用一种策略，尽可能按最佳次序执行要求访问磁盘的诸输入输出请求。-operating system for this experiment : scan, cscan scheduling algorithm simulation disk containing : flowchart design major source so on. Descr iption : disk is a high-speed, high-capacity, rotating type, direct access storage devices. As computer systems support memory, shoulders the heavy task of input and output, multiple procedures in the system design, while there are often a number of requests to visit disk input and output requests pending.
