# Difference between Causal Intervention and Causal Mediation

I'm very new to the area of Causality and I would like some clarity as to the difference between the aforementioned terms.

In the causal diagram $$A \rightarrow B \rightarrow C$$, $$A$$ is the intervention, $$B$$ is the mediator, and $$C$$ is the outcome. This diagram represents a randomly assigned intervention and fully mediation by $$B$$.
