What is a Router and What Does a Router Do? A router is a small device that sits between your modem and computer. Most routers are about the same size and shape as a modem. The purpose of the router is to take the information from the modem and deliver it to your computer. But thatâs not the cool part. What is cool about a router is that itâs able to take this information from several networks and deliver them to several computers.
How Routers Work. In technical terms, a router is a Layer 3 network gateway device, meaning that it connects two or more networks and that the router operates at the network layer of the OSI model. Routers contain a processor (CPU), several kinds of digital memory, and input-output (I/O) interfaces.
