Nodes of term Router

A Router is a device that passes information from one network too another such as the internet. When you have two or more computers connected to each other, that creates a network in and of itself. When two or more Computers connect too the internet those computers are passing data from your (LAN) Local Area Network onto the (WAN) Wide Area Network using a technology built into most routers and firewalls called NAT (Network Address Translation). NAT passes data destined for the WAN interface onto the internet and data destined for the LAN interface to local computers.
