Metcalfe’s Law: A theory argued by Robert Metcalfe, inventor of Ethernet, which states that the power of a network increases by the square of the number of nodes connected to it. For example, where X is the number of nodes, the power of the network is X squared. Metcalfe observed that new technologies are valuable only when large numbers of people use them — consider how less valuable the telephone would be if only two people in the world used them. The network becomes more valuable the more nodes that are connected to it.
