Scan disk scheduling code in c
WebJul 16, 2024 · Algorithm: 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 ...
