disk磁盘调度schedulingdisksplatter Disks Overview of Mass-Storage Structure In this section we present a general overview of the physical structure of secondary and tertiary storage devices. Magnetic Disks Magnetic disks provide the bulk of secondary storage for modern computer systems. Conceptually, disks...
This algorithm is also called the elevator algorithm because of it's behavior. Here, first the head moves in a direction (say backward) and covers all the requests in the path. Then it moves in the opposite direction and covers the remaining requests in the path. This behavior is similar ...
中断驱动I/O中，处理器代表进程发出I/O命令，并继续执行后续指令，当I/O模块完成工作时被中断。DMA技术由DMA模块控制主内存与I/O模块之间数据交换，处理器发送数据块传输请求给DMA模块，整个数据块传输完成后才会被中断。逻辑I/O与设备I/O之间的区别在于，逻辑I/O模块将设备视为逻辑资源，不关心实际...
