The internet is the interconnected computer network that uses Internet protocol suite (TCP/IP) to link billions of devices worldwide creating an “Internet of Things”. This technology can be traced back to the first networked computers and to an early version of the internet called The ARPANET. The ARPANET project led to the development of protocols for internetworking, by which multiple separate networks could be joined into a single network of networks.
