WebArticle Name. SSTF Algorithm Disk Scheduling Algorithms. Description. SSTF Disk Scheduling Algorithm is a disk scheduling algorithm which services requests on the basis of shortest seek time first. SSTF Disk Scheduling Example. It reduces total seek time as compared to FCFS. Author. Akshay Singhal. Publisher Name. WebWhat 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 Read-write ... lee freedom trouser pant-plus
