Question: Which disk scheduling algorithm looks for the track closest to the current head position?

Step 1: - FCFS (First Come First Serve): Serves requests in the order they arrive. - SCAN: Moves head in one direction, servicing requests, then reverses. - LOOK: Similar to SCAN but stops at last request in each direction. - SSTF (Shortest Seek Time First): Selects the request with the minimum seek time from the current head position.

Step 2: Since the question asks for the algorithm that picks the track closest to the current head position, the correct choice is SSTF.
