Queue Visualizer - FIFO Data Structure
Interactive step-by-step visualization comparing linear queues (wasteful) vs circular queues (efficient) with real-world applications.[web:249][web:257]
Linear Queue Problem: Once elements are dequeued, front moves forward and space before it cannot be reused, even if rear reaches the end.[web:257][web:260]

FIFO Principle
- First In, First Out ordering
- Enqueue: Add element at rear
- Dequeue: Remove element from front
- Models real-world waiting lines
Real Applications[web:253]
- CPU & process scheduling
- BFS graph/tree traversal
- Print spooling & job queues
- Network packet buffering
