A router is a networking device that acts as a central point for connecting multiple networks or subnetworks together. It plays a crucial role in directing network traffic, ensuring that data packets are sent to their correct destinations. Think of it as a traffic controller for your digital information. Here's a breakdown of what a router does: Key Functions of a Router:  * Connecting Networks: A router's primary job is to connect different networks.
