The Metcalf's Law states that a networks value is directly proportional to the square of the number of nodes in that network. The nodes can be servers or computers.  

The theory was given by George Gilder in 1993. The law characterizes the various network effects of the networks and communication technologies such as World Wide Web, Social Networking and Internet.

This law is often explained with fax machines.

A single fax machine is not of much value but the value of each fax machine increases if there are more fax machines in the network.

Similarly in the social network the value of the service increases with the increase in the number of the users.
