Witryna16 lip 2024 · SCAN Scheduling algorithm –The disk arm starts at one end of the disk, and moves toward the other end, servicing requests as it reaches each cylinder, until it gets to the other end of the disk. At the other end, the direction of head movement is reversed and servicing continues. The head continuously scans back and forth across … Witryna5. LOOK the disk scheduling algorithm: In this algorithm, the disk arm moves to the 'last request' present and services them. After reaching the last requests, it reverses its direction and again comes back to the starting point. It does not go to the end of the disk, in spite, it goes to the end of requests.

WitrynaC-SCAN Algorithm. C-Scan (Circular Scan) scheduling algorithm is a variant of the SCAN scheduling algorithm designed to provide a more uniform wait time. Note: The disc arm advances from one end of the disc to the other end in the Scan algorithm, completing requests as it hits each cylinder until it reaches the other end of the disc. Witryna1 sty 2015 · Our results and calculations show that, proposed disk scheduling algorithm will improve the performance of disk i/o by reducing average seek time compared to the existing disk scheduling algorithm. For few requests, the seek time and the total number of head movement is equal to SSTF or LOOK scheduling. chinese type 99a main battle tank
