Biconnected components are maximal subgraphs such that the removal of a node (and all edges incident on that node) will not disconnect the subgraph. In graph theory, a component of an undirected graph is an induced subgraph in which any two vertices are connected to each other by paths, and which is connected to no additional vertices in the rest of the graph.For example, the graph shown in the illustration has three components.

The strongly connected components of an arbitrary directed graph form a partition into subgraphs that are themselves strongly connected. The If removing a node increases the number of disconnected components in the graph, that node is called an articulation point, or cut vertex.
