A network is a set of objects (called nodes or vertices) that are connected together. The connections between the nodes are called edges or links. In mathematics, networks are often referred to as graphs (which must be distinguished from an alternative use of the graph to mean a graph of a function).

There's no difference. They're just different words for the same thing, though ?graph? tends to be more common in math and other formal areas, and ?network? more common in more applied areas. What are the vertices and edges of a graph? Vertices are the points, or nodes, of a graph.

In a directed network, connections between nodes are directional. For example, in a Twitter network, Smith might follow Jones but that does not mean that Jones follows Smith. Each directional relationship would have an edge to represent it, typically with an arrow.

Ing to graph theory, any network has a graph (G) representation as G={V, E}, meaning a network consists two components, the vertices (V) and edges (E). Structurally, contact networks are usually weighted networks (i.e., the edges of the network carries weight information).

An undirected network. A directed network. An undirected network where the nodes and edges have different types, as indicated by their colors and line styles. A directed network where the edges and nodes have different weights, as indicated by their sizes.

Contact Graph Routing Contact Graph Routing (CGR) is a dynamic routing system that computes routes through a time-varying topology of scheduled communication contacts in a network based on the DTN (Delay-Tolerant Networking) architecture.

Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter. Each object in a graph is called a node.
