Signaling systems

Signaling systems are networks that transmit information to manage and coordinate activities, like traffic flow or communication between devices. They use various methods—such as electrical signals, light, or sound—to send messages quickly and reliably. In transportation, signaling controls traffic lights and train movements to ensure safety and efficiency. In technology, signaling helps devices communicate data for calls, internet, or other services. Overall, signaling systems are essential for organizing complex processes, making sure that information reaches the right place at the right time to prevent confusion or accidents.
