Name at least 2 methods to reduce thrashing. 6 Explain why wear leveling is important with flash storage. Consider the following requests to read data from sectors of a hard drives, where the current position of the head is at sector 142 and the head is moving towards sector 1. What is the order in which the sectors in the queue would be services using the SCAN disk scheduling algorithm? 32, 94, 6, 33, 2, 24, 184, 101, 438, 89, 538, 21, 271, 476
