Test Your Knowledge About Routers!

A router is a networking device that forwards data packets between computer networks. The main purpose of a router is to connect multiple networks and forward packets to its own networks or other networks. This quiz has been designed to test your knowledge on routers and networking. So, let's try out this quiz. All the best!
