Multi-hop is a way of connecting different pieces of technology like computers, phones, or other devices so that information can travel between them. It's like a chain, with each device in the chain passing the information on to the next one. For example, if a computer and a phone needed to talk to each other, the computer could send a message to the phone through a few different devices. First, the computer sends the message to the first device, then that device passes the message to the second device, and so on until the message reaches the phone. This way, the message can travel a long distance and still be received by the phone.
