WebDirected: A directed graph is a graph in which all the edges are uni-directional i.e. the edges point in a single direction. Weighted: In a weighted graph, each edge is assigned a weight or cost. Consider a graph of 4 nodes as in the diagram below. As you can see each edge has a weight/cost assigned to it.
