Application programming interface (API) is a set of routines, protocols, and tools for building software applications. It's a language and message format used by an application program to communicate with the operating system or some other control program. APIs are implemented by writing function calls in the program, which provide the linkage to the required subroutine for execution.
API is a very important program that almost all software depends on it to perform from the basic use such as accessing the file system to the advance use such as creating a code to prevent hacker. A basic API provides a simple and easy access to the application. A good API can do more than just basic application; it can restrict other vendors from entering into the system.
Programmers are the people that have a very good knowledge of understanding API. Google is one of the companies that make the use of API. Their programmers were able to write secret codes that prevent hackers to get into their system. One of the programs that Google is offering now is the Google Map API. The new Google Map API not only provides you with the basic Google map, it also allows you to create your own map application on your website.
