What is the purpose of network analysis?
Networks comprise graphical representations of the relationships (edges) between variables (nodes). Network analysis provides the capacity to estimate complex patterns of relationships and the network structure can be analysed to reveal core features of the network.

How are service areas created in Network analyst?
Service areas created by Network Analyst also help evaluate accessibility. Concentric service areas show how accessibility varies with impedance. Once service areas are created, you can use them to identify how much land, how many people, or how much of anything else is within the neighborhood or region.
How are lines generated in service area analysis?
The Lines feature class doesn’t provide any inputs to the analysis layer; it serves to store outputs only. Service area lines are not generated by default during a service area analysis, but you can choose to generate them. On the Service Area tab, in the Output Geometry group, set Output Shape Type to Lines or Polygons and Lines .
