WebDisk scheduling algorithms are used to schedule multiple requests for accessing the disk. The purpose of disk scheduling algorithms is to reduce the total seek time. Various disk scheduling algorithms are- In this article, we will discuss about SSTF Disk Scheduling Algorithm. SSTF Disk Scheduling Algorithm- SSTF stands for Shortest Seek Time First. WebMay 8, 2024 · disk scheduling algorithm. In this algorithm, we move the disk arm into a specific direction (direction can be moved towards large value or the smallest value). Each request is addressed that comes in its …
WebDisc 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 request at a time. As a result, other I/O requests need to wait in the waiting queue ... WebScan Algorithm. It is also called as Elevator Algorithm. In this algorithm, the disk arm moves into a particular direction till the end, satisfying all the requests coming in its path,and then it turns backand moves in the reverse direction satisfying requests coming in its path. It works in the way an elevator works, elevator moves in a ...

FCFS disk scheduling algorithm does not cause starvation to any request. In contrast, the request which is far from the head will suffer starvation in the SSTF algorithm. FCFS disk scheduling algorithm increases the total seek time than the SSTF.
