1. Network Complexity and Topology
•   Impact: As the network grows, the complexity increases exponentially. In a fully connected network, the number of potential connections between nodes grows quadratically with the number of nodes. This complexity can lead to difficulties in managing and maintaining the network.
•   Unavoidable Nature: The fundamental nature of networks means that adding more nodes inherently increases complexity.
•   Need to Address: Effective network design and topology optimization are necessary to manage complexity and maintain performance.
