Detailed explanation-1: -Routers operate on the third layer of the OSI Model, the Network-Control Layer. Rather than passing packets based on the Media Access Control (MAC) Layer addresses (as bridges do), a router examines the packet’s data structure and determines whether or not to forward it.
Detailed explanation-2: -Router : Router is a network layer device. It transform the message in the form of packets. It uses routing tables to transfer the data across the network.
Detailed explanation-3: -Layer 3 is the network layer. This is where we send information between and across networks through the use of routers. Instead of just node-to-node communication, we can now do network-to-network communication. Routers are the workhorse of Layer 3-we couldn’t have Layer 3 without them.
