A disk scheduling mechanism in an operating system causes the disk arm to sweepback and forth across the disk suce servicing all requests in its path.This is aA.First Come First ServeB.Shortest Seek Time FirstC.ScanD.None of the above的答案是什么.用刷刷
This article examines the problem of disk scheduling in a multimedia I/O system. In a multimedia server, the disk requests may have constant data rate requirements and need guaranteed service. We propose a new scheduling algorithm, SCAN-EDF, that combines the features of SCAN type of seek ...
OperatingSystemHardDiskDiskSchedulingFuzzyLogicFuzzyInferenceDisk scheduling is one of the main responsibilities of Operating System. OS manages hard disk to provide best access time. All major Disk scheduling algorithms incorporate seek time as the only factor for disk scheduling. The second factor rotat...
A continuum of disk scheduling algorithms, V(R), having endpoints V(0) = SSTF and V(1) = SCAN, is defined. V(R) maintains a current SCAN direction (in or out) and services next the request with the smallest effective distance. The effective distance of a request that lies in the cu...

Although scheduling algorithms with rotation delay in concern are more promising for modern disks, not a single rotation-sensitive algorithm has ever been implemented due to lack of the knowledge of hard drive physical parameters and unawareness of disk head position. In this paper, we present a ...
