Router

A computer networking device that acts as a junction between two networks to transfer data packets among them. A router is essentially different from a switch that connects devices to form a Local Area Network (LAN). Modern high-speed routers are highly specialised computers, generally with extra hardware added to accelerate both common routing functions such as packet forwarding and specialised functions such as IPsec encryption.

Routers can be classified as edge and core. A router that connects clients to the Internet is called an edge router. A router that serves solely to transmit data between other routers, e.g. inside the network of an Internet service provider, is called a core router.
