Scan and cscan disk scheduling

WebApr 21, 2024 · The circular SCAN (C-SCAN) scheduling method is a modified version of the SCAN disc scheduling technique that addresses the SCAN algorithm's inefficiency by more equitably serving requests. C-SCAN, like the SCAN (lift algorithm), moves the head from one end to the other, fulfilling all requests. WebThe C-Scan scheduling algorithm is an enhanced version of the Scan algorithm. It ensures a consistent waiting time. The head moves from one end of the disc to the other, satisfying all requests. Compared to the Scan Algorithm, the waiting time for the cylinders just visited by the head decreases.
