Question
What is the primary goal of disk scheduling in operating
systems?Solution
Disk scheduling is a technique used in operating systems to manage and optimize the order in which disk I/O operations are performed. The primary goal of disk scheduling is to improve the efficiency of data retrieval and write operations on the disk. By optimizing the sequence of read and write requests, disk scheduling reduces the time the disk's read/write head spends moving between different tracks, thus minimizing disk seek time and rotational latency. This leads to better overall system performance and responsiveness. Disk scheduling does not directly influence CPU utilization or memory management, although efficient disk access can indirectly contribute to better system performance and resource utilization.
