Connectivity refers to the structure of a network. Only when an entity is connected, i.e., having become a node of a network, can it be accessed. Connectivity studies problems related to naming and topology, such as the following:
- How to name the nodes of a network? How to find a specific node? How to refer to a specific node?
- How are the nodes interconnected? Does the network structure change over time? Is the network static, dynamic, or evolutionary?
