Web' Disk Scheduling Algorithm ' is an algorithm that keeps and manages input and output requests arriving for the disk in a system. As we know, for executing any process memory is required. And when it comes to accessing things from a hard disk, the process becomes very slow as a hard disk is the slowest part of our computer. Web* Disk Scheduling First-Come, First-Served (FCFS) Requests are serviced in the order they arrive, without regard to the current position of the heads Shortest-seek-time-first (SSTF) Disk heads are moved the minimum amount possible to satisfy a pending request Scan Disk heads continuously move in and out servicing requests as they are encountered …
