• Routers: A Router is a networking device that forwards data packets between computer networks. One or more packet switched networks or subnetworks can be connected using a router. By sending data packets to their intended IP addresses, it manages traffic between different networks and permits several devices to share an Internet connection.

Hardware which can send and receive data, instructions, and information is known to as a communications device. let’s understand about communication devices in detail.
