@Babloo

API is abbrevated as Application Programming Interface..

It can be said as a package which provides programmers with set of functions... which itself are programmed to provide basic functionalities as set of functions

Suppose take an example as bare hardware... which a programmer finds less comfortable to code directly to access it or work on it....

Mean while he writes lines of codes as set of functions which provides required basic functionalities on bare hardware...so that fellow programmers can just call these fuctions directly to get work done......

Yes Anurag is correct.
API's are set of commonly used functions.
So it is like repository of commonly(mostly) used function.
