Question 1
Given the requests 75, 30, 200, 180 starting at 100, calculate total head movement for SCAN and C-SCAN and explain which is more efficient.
💡 Hint: Calculate each move step-by-step and compare.
Question 2
If you were to implement an IO queue with random arrival times for requests, discuss which disk scheduling algorithm would most likely suffer from starvation, and give an example.
💡 Hint: Consider how arriving requests can overlap.
