DiskScheduling Algorithm 磁盘调度在多道程序设计的计算机系统中，各个进程可能会不断提出不同的对磁盘进行读/写操作的请求。由于有时候这些进程的发送 请求的速度比磁盘响应的还要快，因此我们有必要为每个磁盘设备建立一个等待队列，常用的磁盘调度算法有以下四种： 先来先服务算法（FCFS）， 最短寻道时间优先算法（...
Which in turn decides how fast the programs written for that system respond, increasing the overall system storage and retrieval performance benchmark The proposed disk scheduling algorithm reduces the average head movements over the disk drive's lifetime by following a sinewave pattern around the ...

We introduce a new deadline driven disk scheduling algorithm designed for multimedia servers. The proposed algorithm supports real time requests with multiple priorities, e.g., those for different object classes in digital library applications. The proposed algorithm enhances utilization of disk bandwidth...
1. FCFS Scheduling Algorithm This is a simple scheduling algorithm which means first come first serve form of an algorithm. This kind of algorithm generally not provides the fastest service. Consider the example: a disk queue with a request for I/O to blocks on cylinder 97, 182, 37, 128,...
