WebDisk Scheduling Algorithms: Disk scheduling algorithms are the algorithms that are used for scheduling a disk. There are five types of Disk Scheduling Algorithms are … WebThe C-SCAN (Circular Scan) scheduling algorithm is a variant of the SCAN scheduling algorithm designed to provide a more uniform wait time. Like SCAN, C-SCAN moves the head from one end of the disk to the other, servicing requests along the way.

WebApr 1, 2024 · Seek Time: A disk is divided into many circular tracks. Seek Time is defined as the time required by the read/write head to move from one track to another. Example, Consider the following diagram, the read/write head is currently on track 1. 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. craft short story winner
