Disk Scheduling Algorithm Visualization

An interactive visualization tool for demonstrating and comparing different disk scheduling algorithms. Supports three classic disk scheduling algorithms: FCFS (First Come First Serve), SSTF (Shortest Seek Time First), and SCAN (Elevator Algorithm).

Features

• Intuitive disk head movement visualization
• Real-time display of seek time and current position
• Support for three classic disk scheduling algorithms:
  • FCFS (First Come First Serve)
  • SSTF (Shortest Seek Time First)
  • SCAN (Elevator Algorithm)
• Algorithm performance comparison table
• Detailed algorithm characteristics explanation
• Responsive design, mobile device support

Usage

1. Set initial head position (0-199)
2. Input request queue (comma-separated numbers)
3. Select SCAN algorithm initial direction (Left/Right)
4. Click corresponding algorithm button to start demonstration
5. Use reset button to restart demonstration
6. View comparison table to understand performance differences between algorithms
