A router forwards data packets between independent networks. They perform traffic directing functions. A router is commonly known to contain a routing table that lists the preferred routes between any two or more systems in an interconnected network. Technically, when a packet arrives, the router thinks through the next best route to send the packet.

Answer:

The router is a device that knows how to forward traffic between independent networks.

Explanation:

Routing is a process of selecting a direction for traffic in a network or selecting a direction for traffic in multiple networks.

Generally, routing is implemented in many types of networks like circuit-switched networks and public switched telephone networks and computer networks like the Internet.

The routing process commonly keeps forwarding based on routing tables, which maintain a record of the routes to various network targets.
