An application programming interface (API) is a software program that facilitates interaction with other software programs.
An API allows a programmer to interact with an application using a collection of callable functions. The goal of an API is to allow programmers to write programs that will not cease to function if the underlying system is upgraded.
An API can be language dependent or independent:-
- Language Dependent:- This means it is only available by using the syntax and elements of a particular language, making it more convenient to use.
- Language Independent:- This means the API is written to be called from several programming languages.
API libraries and frameworks
An API is usually related to a software library: the API describes and prescribes the expected behaviour while the library is an actual implementaion of this set of rules. A single API can have multiple implementations (or none, being abstract) in the form of different libraries that share the same programming interface.
An API can also be related to a software framework: a framework can be based on several libraries implementing several APIs, but unlike the normal use of an API, the access to the behavior built into the framework is mediated by extending its content with new classes plugged into the framework itself. Moreover the overall program flow of control can be out of the control of the caller, and in the hands of the framework via inversion of control or a similar mechanisms.
A device API is an application programming interface (API) that allows developers to create Web applications that interact with device hardware. A device API basically allows end users to use their hardware to interact with the Web in ways beyond what is allowed by standard Web browsers.
