Router

Routing achieved commercially popularity in the mid - 1980s - at a time when large-scale Internetworking began to change the fairly simple, homogeneous environments. Routing is the act of moving information across an Internetwork from a source to a destination. It is often contrasted with bridging, which perform a same function. Routers use information within every packet to route it from one LAN to another, and communicate with each other and share information that permits them to verify the best route by a complex network of many LANs.
