Simulators

Disk scheduling simulator

Enter the requested cylinders in the order they arrived and where the head starts, choose an algorithm and the direction the arm is moving, and see its path drawn in the order it moves, with the distance of every move and the total head movement.

The simulator

Disk scheduling simulator: how to use it

Supports FCFS, SSTF, SCAN, C-SCAN, LOOK and C-LOOK, so you can compare them on the same queue.

Lessons that use it

  • Disks and disk scheduling (Operating Systems)How a hard disk finds data (seek, rotation, transfer), the FCFS, SSTF, SCAN, C-SCAN, LOOK and C-LOOK algorithms, what changes with SSDs, and RAID.
