Definition:Bridge (Graph Theory)

Definition
Let $G = \left({V, E}\right)$ be a connected graph.

Let $e \in E$ be an edge of $G$ such that the edge deletion $G - e$ is disconnected.

Then $e$ is known as a bridge of $G$.

Example
In the graph below, $CD$ is a bridge.

The graph would be separated into the two components $ABC$ and $DEF$.
