The Appearance Menu
Here is where you 
- “Activate” newly installed themes
- Manipulate the widgets installed into your choice of Widget areas . . . side columns or areas in the bottom footer area
- Create new menus or edit menus you already have. Menus are of course your page links or other links and are common to all pages on your website
- Background, Header, Editor are for changing your theme if your theme allows it in this area.
The Themes, Widgets and Menus have their own pages for more in depth information.
