An API is an Application Interface. API's are often used connected to in order to retrieve data. An example of an API would be Gravatar. Gravatar stores users profile pictures which they associate to an MD5 hash of the users email address. How would this API work? 1) Make a GET request to the API using a key, secret or in this case, a users MD5 hashed email address. 2) The API will process this request and then return the associated profile picture.

Hopefully this clears some of it up.

If it didn't then here is the definitely pulled from google:

An application programming interface is a connection between computers or between computer programs. It is a type of software interface, offering a service to other pieces of software. A document or standard that describes how to build or use such a connection or interface is called an API specification.
