A router is a device that connects multiple networks together and routes network traffic between them.
It forwards data packets between computer networks, creating an overlay internetwork.
A router is connected to two or more data lines from different IP networks.
When a data packet comes in one of the lines, the router reads the network address information in the packet header to determine the ultimate destination.

A router is a network device that operates at the network layer (Layer 3) of the OSI model and is responsible for forwarding data packets between different networks. Its primary function is to determine the optimal path for data transmission based on the destination IP address in the packet header.
