SCAN (Scanning) is a disk scheduling algorithm used in operating systems to manage disk I/O operations. The SCAN algorithm moves the disk head in a single direction and services all requests until it reaches the end of the disk, and then it reverses direction and services all the remaining requests. In SCAN, the disk head …

WebApr 1, 2024 · Seek Time: A disk is divided into many circular tracks. Seek Time is defined as the time required by the read/write head to move from one track to another. Example, Consider the following diagram, the read/write head is currently on track 1. WebFSCAN 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.
