Question

Which disk scheduling algorithm is better for systems that places a heavy load on the disk and less likely to cause starvation problem?

• A. SCAN
• B. FCFS
• C. SSTF
• D. SJF

Hint:

SCAN = Elevator algorithm; handles heavy loads and prevents starvation.

Answer 1

The Correct Option is A

The SCAN algorithm moves the disk arm toward one end, servicing requests, then reverses direction. It avoids starvation by servicing in both directions.
