Detailed explanation-1: -Data sent over the internet is called a message, but before messages get sent, they’re broken up into tinier parts called packets. These messages and packets travel from one source to the next using Internet Protocol (IP) and Transport Control Protocol (TCP).
Detailed explanation-2: -The router uses the information in the IP header to decide whether and where to forward each received packet, and which network interface to use to send the packet. Most packets are forwarded based on the packet’s IP destination address, along with routing information held within the router in a routing table.
Detailed explanation-3: -When a router receives a packet, the router checks its routing table to determine if the destination address is for a system on one of it’s attached networks or if the message must be forwarded through another router. It then sends the message to the next system in the path to the destination.
