nodes; can have attributes like gender, location, start/end time

edges; can have attributes like weight, start/end time

edges can be directed with a source and target (type of edge -- directed or undirected)

network or graph: refers to all nodes inside, in aggregate

isolates: unconnected nodes

path of nodes through network

component: aspect of nodes linked together

vocabulary: http://barabasilab.neu.edu/courses/phys5116/content/Class2_NetSci_2012/02_Class_2012_Graphs.pdf

adjacency matrix; 1 indicates connection, 0 indicates no connection; grid showing links; can be weighted by using non-binary numerals; directed or undirected

node table: gives attributes to nodes; edge table links together source, target, and weight

when not to use a network: too much data (structure is not visible); when you have entities but aren't sure of relationships
