The number of possible connections on a network is N(N–1) or N2 –N N = number of nodes (points of connection) Example: 10 computers on a network = 10(10–1) = 10x9 = 90 possible connections Metcalfe’s Law The usefulness, or utility, of a network equals the square of the number of users The more users on a network, the more useful it becomes Early on, changes in technology only affect the .
