Layer 3 Networking

Layer 3 networking refers to the network layer in the OSI model, responsible for routing data between different devices across networks. It focuses on how data packets travel from their source to destination, regardless of the underlying physical network. This layer uses logical addressing, like IP addresses, to identify devices and networks, enabling efficient communication. Routers operate at this layer, directing traffic based on these addresses, and ensuring that data reaches the correct location, even if that involves passing through multiple networks. Essentially, Layer 3 networking manages how information flows through interconnected networks globally.
