A simple router connects homogeneous and heterogeneous networks to create what is called an Internetwork. The typical router is a box with two or more ports, each of which is connected to a separate network or a subnet, which is a defined section of a network.
Routers operate at the 3rd layer of the OSI Model, titled the Network layer. The routers are intelligent devices, and examine network traffic to determine if network information is ready to be passed over a cable.
