Question: In Angular 2, it says there are two types of components 

1) Container Components
2) Presentational Components

I would like to know more about container components.

Answer: 
Container components, or smart components, are usually the pages you route to. 

They contain service methods to load and manipulate data and pass content to the presentational, or dumb, components inside them.
> 
> Containers: contains stateful, and often routable, components that pass down data and behaviour-encapsulating callbacks to presentational components (and sometimes other containers).
