WebAug 16, 2024 · Disk scheduling is done by operating systems to schedule I/O requests arriving for the disk and the algorithm used for the disk scheduling is called Disk Scheduling Algorithm. In this post, we will discuss the SCAN Disk Scheduling Algorithm and also write a program for SCAN disk scheduling algorithm. WebApr 7, 2024 · SCAN. SCAN (Scanning) is a disk scheduling algorithm used in operating systems to manage disk I/O operations. The SCAN algorithm moves the disk head in a single direction and services all requests until it reaches the end of the disk, and then it reverses direction and services all the remaining requests.

"WebIn contrast, the C-SCAN disk scheduling algorithm offers a uniform waiting time when requesting the locations. SCAN services all the requests in forward and reversed directions. In contrast, the C-SCAN disk scheduling services the requests in a single direction only. SCAN has higher throughput and gives a low variance response time. " - Disk scheduling algorithm scan
