Explain disk scheduling algorithms-shortest seek time first, Operating System

Assignment Help:

SSTF (Shortest Seek Time First)

After a demand go to the closest request in the work queue regardless of direction
Decrease total seek time compared to FCFS
Disadvantages
Starvation is probable stay in one area of the disk if very busy
Switching directions deliberates things down
