"Web2 Answers. Connected is usually associated with undirected graphs (two way edges): there is a path between every two nodes. Strongly connected is usually associated with directed graphs (one way edges): there is a route between every two nodes. Complete graphs are undirected graphs where there is an edge between every pair of nodes. " - Graph theory-connected components
