A router refers to a networking device useful in forwarding data packets or traffic directing of the internet between computer networks to the final destination.

Voice over Internet Protocol (VoIP) is a software and hardware technology that allows individuals to make telephone voice calls through the use of a broadband internet connection (IP) rather than a regular (traditional) phone line.
