What key mechanism in the Barabási–Albert model leads to the emergence of highly connected hub nodes in a network?
Preferential attachment, where new nodes are more likely to connect to nodes with higher degree
Random attachment, where new nodes connect to existing nodes uniformly at random
Nodes connect only to their immediate neighbors without preference

What key mechanism in the Barabási–Albert model leads to the emergence of highly connected nodes in a network?
Preferential attachment, where new nodes are more likely to connect to already highly connected nodes
Random attachment, where new nodes connect to existing nodes with equal probability
Periodic rewiring of connections to balance node degrees
