According to Metcalfe's law, if a second computer is joined to a first, the value of the network created is how many times great
Nataly_w [17]

Answer:

Four times

Explanation:

Metcalfe's Law is a theory used in digital networks and telecommunications to symbolize the value of a network. According to the law a network's impact is the square of the number of nodes in that network at that given time. For instance, if a network has 10 nodes, its intrinsic value will be 100 (10 * 10).

The law also states that if a second computer is connected to a first, the value of the network created will be four times bigger than the value of the original computer.
