Pulse-coupled networks are collections of computers or other types of devices that are connected together to share information. Each computer (or device) in the network sends out regular pulses of information to the other computers, and the pulses travel through the network and “couple” together. That means that when one computer sends out a pulse, the other computers will receive the same pulse, and it will travel through the network until it gets back to the source. This way, all the computers in the network know how each other is doing and can communicate with each other.
