The Elevator algorithm, also known as the SCAN algorithm, is a disk scheduling algorithm used by operating systems to manage and optimize the read and write requests to a hard disk drive (HDD). The main goal of this algorithm is to minimize the movement of the disk's read/write head, thereby improving the overall efficiency and speed of disk operations. \#\#\# How the Elevator Algorithm Works 1.
