What Is a Router ?

A router is a device that plays a major role in computer networking. It can collect data packets from computers and then based on their addresses, forward them to their destinations.

Routers are used to connect two or more networks which could include a Local Area Network(LAN) or a Wide Area Network(WAN). They are responsible for correctly routing the data between computers, hence the name 'router'.

Routers play a significant role in ensuring the proper functioning of the Internet, which is a network of networks. They work with the Internet Protocol(IP) to forward the packets across millions of computers.
