Scientists use computer programs to analyze networks because networks are often very complex. Students use the computer program Cytoscape to analyze the cell phone network.

A network is a system of interconnected parts. These parts may be organisms, genes, molecules, etc…Nodes are the parts of a network, and edges are the relationships between those parts of the network

This is our introductory module that we recommend teaching before each of our other modules to give students a background in systems.
