Are event listeners and event handlers the same?

Hi All,

Any thoughts/pointers/reference articles regarding this will be helpful.

Basically event listeners are created using event handlers. ex: replication listener [1]

A listener watches for an event to be fired. In AEM - you can write Listener code using this API:

The handler is responsible for dealing with the event. For example - perform a custom action. 

See this article to learn how to work with listeners/events in AEM:
