SCAN Disk Scheduling Algorithm - Coding Ninjas

WebSep 29, 2024 · In the C-SCAN disk scheduling algorithm, the head starts from one end of the tracks and moves towards the other end, servicing requests in between. When we reach another end, the direction is reversed head moves towards its starting position without satisfying any request. So we have motions in two directions. WebLOOK Disk Scheduling Algorithm is an improved version of the SCAN Disk Scheduling Algorithm. It overcomes the disadvantage of SCAN Disk Scheduling Algorithm. It does not causes the head to move to the ends when there are no requests to be serviced. Author Akshay Singhal Publisher Name Gate Vidyalay Publisher Logo 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. cost of hp smartfriend
