Disk Scheduling Algorithm Visualizer

This interactive tool lets you visualize the FCFS, SCAN, CSCAN, LOOK, C-LOOK, and SSTF disk scheduling algorithms in action. Adjust parameters, view real-time metrics, and see how scheduling decisions impact performance. Select an algorithm below, or see how the 6 algorithms compare with a single data set. This website was made for COMP 3659 at Mount Royal University.

FCFS

First-Come, First-Served scheduling algorithm.

SCAN

SCAN scheduling algorithm.

CSCAN

C-SCAN scheduling algorithm.

LOOK

LOOK scheduling algorithm.

C-LOOK

C-LOOK scheduling algorithm.

SSTF

Shortest Seek Time First scheduling algorithm.

Initial Head Position (0 - 199)

Comparison for all Algorithms

This graph compares the performance of six different disk scheduling algorithms: FCFS, SCAN, CSCAN, LOOK, C-LOOK, and SSTF. Each algorithm is run simultaneously, and their results are plotted on the graph with distinct colors. The x-axis represents the disk request sequence, while the y-axis implies the seek time as it increases.
