So what does a router do in a network? How does a router work? We answer these and more questions in this article To put it simply, a router connects devices within a network by forwarding data packets between them. This data can be sent between devices, or from devices to the internet.

The router does this by assigning a local IP address to each of the devices on the network. This ensures that the data packets end up in the right place, rather than getting lost within the network. Imagine this data as a courier package—it needs a delivery address so that it ends up at the right recipient.

Your local computer network is like a suburban road—just knowing this location within the world at large i. The package could easily end up at the wrong house with limited information. Thus, the router makes sure that each location device has a unique number so that the package goes to the right address.

You need a modem due to the different types of signals used by computers compared to the internet at large. Computers and mobile devices use a digital signal, while the internet works on an analog signal.
