What are routers?

A router is a type of device which allows connection and/or access to the network. They are the ones that allow various devices to connect to the network, primarily the Internet.

Officially, a router is a device that determines the best way for a packet to be forwarded to its destination. In some cases, software on a computer can also act as a router. A router acts as a dispatcher as it decides which way to send each information packet.

The router can be located at any gateway, i.e. where one network meets another. This includes each point-of-presence on the internet. A router is also often included as part of a network switch.
