Router
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.
