Layer 3 Routers

A Layer 3 router is a device that directs data traffic between different networks, similar to a traffic controller for the internet. It uses network addresses (like IP addresses) to determine the best path for data to reach its destination. Think of it as a map navigator that helps data packets find the most efficient route across various networks, ensuring they arrive at the right location. Layer 3 routers are essential for connecting local networks to the broader internet and managing data flow efficiently across complex systems.
