Answer: The device you are describing is commonly known as a router. A router is a networking device that forwards data packets between computer networks. It connects different networks, such as local area networks (LANs) and wide area networks (WANs), and directs data traffic based on the destination IP addresses of the packets.Routers use routing tables and protocols to determine the best path for forwarding the packets, ensuring efficient communication between devices on different networks. They can also provide additional features such as network address translation (NAT), firewall protection, and wireless connectivity.
