WebAug 29, 2024 · The C-Scan disk scheduling algorithm is a disk scheduling algorithm that is designed to ensure that all jobs get the minimum amount of processor time. It achieves this by ensuring that each job is allocated enough time to complete its execution, known as the completion time. The idea behind this algorithm is to scan through the list … WebIntroduction. Before studying the SCAN algorithm, we must know what disc scheduling is.

WebApr 5, 2024 · Here's an example of how the FCFS disk scheduling algorithm works: Suppose there are four I/O requests, R1, R2, R3, and R4, arriving in the following order − R1: track 10 R2: track 22 R3: track 15 R4: track 28 Assuming the disk head is initially at track 20, the queue for servicing these requests will look like this − Queue: R1, R2, R3, R4 make a rogers accountWebFSCAN is a disk scheduling algorithm to determine the motion of the disk's arm and head in servicing read and write requests. It uses two sub-queues. During the scan, all of the requests are in the first queue and all new requests are put into the second queue.Thus, service of new requests is deferred until all of the old requests have been processed. make a robot and fight
