WebMar 18, 2024 · The operating system needs to manage the hardware efficiently. To reduce seek time. To perform disk scheduling, we have six disk scheduling algorithms. These are-. The goal of the disk scheduling algorithm is-. Have a minimum average seek time. Have minimum rotational latency. Have high throughput. WebC Look Scheduling. C Look Algorithm is similar to C-SCAN algorithm to some extent. In this algorithm, the arm of the disk moves outwards servicing requests until it reaches the highest request cylinder, then it jumps to the lowest request cylinder without servicing any request then it again start moving outwards servicing the remaining requests.
