Definition: A connection between two vertices of a graph. In a weighted graph, each edge has an number, called a "weight." In a directed graph, an edge goes from one vertex, the source, to another, the target, and hence makes connection in only one direction.
Also known as arc.

Note: That is, in a directed graph, an edge goes from the source to the target.
