Since as per the above list, component itself act as direcitves. So as a programmer, it is very common to assume that component and direcitves are the same. But actually it is not true. Below the comparison of the Directives and component.
| Component | Directives |

| Component is a directive which uses shadow DOM to create encapsulated visual behavior called components. Components are typically used to create UI widgets | Directive is used to add behavior to an existing DOM element |
| Component is used to break up the application into smaller components. | Directive is use to design re-usable components. |
| Only one component can be present per DOM element. | Many directives can be used per DOM element. |
| @View decorator or templateurl template are mandatory in the component. | Directive doesn’t use View. |
