Router
ROO-ter
/ˈruːtər/
A networking device that forwards data packets between computer networks, connecting local area networks (LANs) to wide area networks (WANs) like the internet.
It intelligently directs data packets along the most efficient 'route' to their destination.
The story behind the word. The word 'Router' is derived directly from the verb 'to route,' which means to direct along a particular course or path. The suffix '-er' denotes an agent or device that performs an action. So, a router is quite literally a device that 'routes' data packets. It's the traffic controller of the internet, ensuring that your emails and cat videos find their way through the vast network of connections.
