difference between webdriver and eventfiringwebdriver

EventFiringWebDriver is a wrapper around an arbitrary WebDriver instance which supports registering of a WebDriverEventListener, e.g. for logging purposes.

I am unable to understand the difference,can you say by giving  examples

EventFiringWebDriver is also a concrete implementation of the WebDriver, but what it does is, it doesn’t implement the WebDriver directly, but binds itself to an existing object of any of the webdrivers listed above, and then when used, it triggers events. So using EventFiringWebDriver you can listen to events such as before text is changed, after text is changed, before url is loaded etc., and choose to do something with the EventFiringWebDriver.
