The symbol types are: 1. Graphic symbols, which can be used for static images and creating reusable animation clips connected to the main timeline; 2. Button symbols, which can be created to respond to mouse clicks, slides, or other Interactive buttons for actions; 3. Movie clip components, which can create reusable animation clips.

Buttons, movie clips and graphic components.
Graphic symbols can be used for static images and can be used to create reusable animation clips connected to the main timeline.
Graphic components run synchronously with the main timeline. Interactive controls and sounds do not work during animation sequences of graphic symbols. Because there is no timeline, graphic symbols are smaller in FLA files than buttons or movie clips.
Using the button symbol, you can create interactive buttons that respond to mouse clicks, slides, or other actions.
You can define graphics associated with various button states and then assign actions to button instances.
Using movie clip components, you can create reusable animation clips.
Video clips have multiple frame timelines that are independent of the main timeline. You can think of multi-frame timelines as nested within the main timeline, and they can contain interactive controls, sounds, and even other movie clip instances.
You can also place movie clip instances within the button symbol's timeline to create animated buttons. Additionally, movie clips can be adapted using ActionScript™.
