What is Network?
The Network layer is the third layer of the OSI model, responsible for logical addressing and routing data packets between devices across different networks. It uses IP addresses to determine the best path for data to travel from source to destination. Routers operate at this layer, making forwarding decisions based on routing tables and protocols.
