window, navigator
- BOM - Browser Object Model
  - navigator represents the the browser basic code (or kernel) and properties, like version, user agent string, language, geolocation options and so on.
  - window is a "god object" containing all browser components, such as the address bar (window.location), modal dialogues (alert(), prompt()) and the window being displayed on screen itself. It's also the top object where all global variables are assigned to.
document
- DOM - Document Object Model
- Contains all of the content being displayed - in other words, whatever is inside the window.
The document represents all content as nodes - tags, text, images, and so on.
