Data Network Conceptual Models

A Data Network is a telecommunications network that allows exchange of data. Networked computing devices pass data to each other along data connections. Data is transferred in the form of packets. The connections (network links) between nodes are established using either cable media or wireless media. The Internet is the best known Data Network, but it is thought that the Internet will have to be drastically changed, modified or added on to in order to accommodate the Internet of Things.
