Disk management is another major focus of the course, where you’ll learn about disk scheduling algorithms, RAID structures, and file system organization. The course emphasizes important aspects of file sharing and protection mechanisms to ensure secure and efficient file access and management. ...
5.4.3 Disk Arm Scheduling Algorithms First, consider how long it takes to read or write a disk block. The time required is determined by three factors: 1. Seek time (the time to move the arm to the proper cylinder). 2. Rotational delay (the time for the proper sector to rotate under...

Scheduling algorithms There is a wide choice of scheduling algorithms that can be selected, depending upon the desired outcome and the mix of work which the system is designed for. The most commonly used are • First-in first-out (FIFO): this implies a queue ordered by a starting time st...
