Which disk scheduling algorithm selects the disk request that is closest to the current position of the disk head?
Options
- A. FCFS
- B. SSTF
- C. SCAN
- D. More than one of the above
- E. None of the above
Quiz Practice:
B. SSTF
Explanation: SSTF (Shortest Seek Time First) selects the pending request that requires the minimum head movement from the current disk-head position. It can provide lower average seek time than FCFS, but distant requests may suffer from starvation.
