Queue • Real World Architecture

Applications of Queues

Any time you need to manage resources in a fair, sequential, First-Come-First-Served manner, a Queue is the ideal data structure.

Operating Systems (CPU Scheduling)

The OS maintains a "Ready Queue" of processes waiting for CPU time. In Round Robin scheduling, processes are dequeued, given a time slice, and then enqueued back to the rear.

Network Buffers

Routers and switches use queues to hold packets of data arriving faster than they can be processed. If the queue overflows, packets are dropped (packet loss).

Breadth-First Search (BFS)

In graph traversal, a queue ensures that you visit all nodes at the current depth level before moving deeper. This guarantees finding the shortest path in an unweighted graph.
