Network Functions
Definition: A network is a set of interconnected linear features that form a pattern or framework. They are commonly used for moving resources from one location to another.
Network Analysis Network analysis is commonly used for the analysis of moving resources from one location to another through a set of interconnected features. It includes determination of optimum paths using specified decision rules.

Networks
When nutrients from farmland are running off into streams, it is important to know in which direction the streams flow and which streams empty into other streams. This is done by using a linear network.
network -- a graph without two dimensional objects. If projected onto a two-dimensional surface, a network can have either more than one node at a point and (or) intersecting links or chains without corresponding nodes.
Network Analysis is a range of techniques employed by engineers and planners to study the properties of networks including connectivity, capacity, and rates of flow.
