connected components of a graph

PDF	Connected Components Intuitively a connected component is a “piece” of a graph in the sense we just talked about Question: How do we know that this particular definition of a “piece” of a graph is a good one? Goal: Prove that any graph can be broken apart into dif erent connected components

What is the difference between a connected graph and a disconnected graph?
A component is a maximal connected subgraph. This means it is a connected subgraph that cannot be extended by including any other vertices and/or edges in the whole graph without losing its connectedness. A connected graph has exactly one component, which is the graph itself. A disconnected graph has at least two components by definition.
How do you know if a graph is connected?
A graph is connected if and only if it has exactly one connected component. The strong components are the maximal strongly connected subgraphs of a directed graph. A vertex cut or separating set of a connected graph G is a set of vertices whose removal renders G disconnected.
What is a component of an undirected graph?
In graph theory, a component of an undirected graph is a connected subgraph that is not part of any larger connected subgraph. The components of any graph partition its vertices into disjoint sets, and are the induced subgraphs of those sets. A graph that is itself connected has exactly one component, consisting of the whole graph.
Is a connected component a piece of a graph?
Intuitively, a connected component is a “piece” of a graph in the sense we just talked about. Question: How do we know that this particular definition of a “piece” of a graph is a good one? Goal: Prove that any graph can be broken apart into dif erent connected components.
