WitrynaSCAN Disk Scheduling Algorithm-. As the name suggests, this algorithm scans all the cylinders of the disk back and forth. Head starts from one end of the disk and move towards the other end servicing all the requests in between. After reaching the other end, head reverses its direction and move towards the starting end servicing all the ... WitrynaWhat is SSTF disk scheduling:-. Shortest seek time first (SSTF) algorithm selects the disk I/O request which requires the least disk arm movement from its current position regardless of the direction. It reduces the total seek time as compared to FCFS. Example:-: Given the following queue -- 95, 180, 34, 119, 11, 123, 62, 64 with the … can crypto be tracked
