Disk scheduling is a method used by operating systems to manage how data is read from and written to a hard disk drive or solid-state drive. Since these storage devices have limited access times, efficient scheduling helps minimize delays and improve overall system performance. Different algorithms, such as First-Come, First-Served (FCFS) and Shortest Seek Time First (SSTF), determine the order in which requests are processed. By optimizing the sequence of read and write operations, disk scheduling enhances data retrieval speed and reduces wear on the storage medium.
