router
In computing, a device that pushes traffic through a packet-switched network. On the Internet, traffic travels through a series of routers that relay each packet of data to its destination by the best possible route.
A router is a device that may be used to connect two or more networks together, or to connect a network to the Internet. The router receives packets of data on the network and uses headers and forwarding tables to direct these packets to the appropriate network interface.
