WebC-SCAN algorithm. In C-SCAN algorithm, the arm of the disk moves in a particular direction servicing requests until it reaches the last cylinder, then it jumps to the last cylinder of the opposite direction without servicing any request then it turns back and start moving in that direction servicing the remaining requests.

WebIntroduction. Before studying the SCAN algorithm, we must know what disc scheduling is. Disc Scheduling: The operating system performs a disc scheduling process to schedule I/O requests that arrive at the disc. Disc scheduling is important since-Many I/O requests may arrive from different processes, and the disc controller can only serve one I/O … WebWhat is Look disk scheduling:-. It is similar to the SCAN disk scheduling algorithm except for the difference that the disk arm in spite of going to the end of the disk goes only to the last request to be serviced in front of the head and then reverses its direction from there only. Thus it prevents the extra delay which occurred due to ...
