Explanation: 

Detailed explanation-1: -A primary function of a router is to determine the best path to use to send packets. To determine the best path, the router searches its routing table for a network address that matches the destination IP address of the packet.

Detailed explanation-2: -Computers send the first packet to the nearest router. A router is a type of computing device used in computer networks that helps move the packets along.

Detailed explanation-3: -A routing protocol is a set of rules that specify how routers identify and forward packets along a network path. Routing protocols are grouped into two distinct categories: interior gateway protocols and exterior gateway protocols.

Detailed explanation-4: -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.
