Bindings are rules that define the relationship between exchanges and queues. They tell the exchange which queues should receive messages based on routing criteria. Components of a binding:
Queue: The destination queue
Exchange: The source exchange
Routing key: Pattern used for routing (for direct and topic exchanges)
Arguments: Additional parameters for complex routing
# Example: Bind queue to exchange with routing key
rabbitmqctl bind_queue exchange_name queue_name routing_key
