Metcalfe's Law  Concept
"The power of the network increases exponentially by the number of computers connected to it. Therefore, every computer added to the network both uses it as a resource while adding resources in a spiral of increasing value and choice."
 Bob Metcalfe
Metcalfe's Law is expressed in two general ways:
 The number of possible crossconnections in a network grow as the square of the number of computers in the network increases.
 The community value of a network grows as the square of the number of its users increase.
