Disk scheduling: In a computer, multiple processes run over the same time. To handle this multiple processes, the operating system decides which process has to be executed first. This technique is called as disk scheduling. There are different types of scheduling algorithms. They are as follows: First-come, First-served (FCFS) Shortest-Seek-Time-First (SSTF) SCAN Shortest-Seek-Time-First disk scheduling algorithm (SSTF): This algorithm processes the requests based upon the shortest distance. The algorithm first moves the head to the shortest distance it need to satisfy from the pending requests. The head movement changes the directions after each request is processed.
