    • In a random network, the average node sets the scale of the network, which means that most nodes have about the same number of links as the average node. For networks that follow Eq. 1, for γ < 3 the second moment of the distribution diverges, which means that the average is not characteristic because the error bars characterizing our uncertainty about its value are infinite. These networks lack a characteristic scale; hence, they are called scale-free. Formally, networks whose degree distribution follows Eq. 1 are called scale-free networks

    • The small-world property refers to the fact that in many networks the average node to node distance is rather small, of the order of log N, where N is the number of nodes in the network
