A Brief Discussion on API & API Full Form in Computing
API is a fantastic technology widely used by web developers and programmers to make things or resources over the internet secure and smoother. API Full-Form can be stated as the Application Program Interface. There are many advantages one can find if he/she chooses to use API.
API Full Form is Application Program Interface. API works as a mediator or communicator between two or more programs on behalf of the developer or user. Application Program Interface is the full form of API that is the way for an application to interact with a particular operating system, or mobile application.
Purpose of API:
During Application building API simplifies programming by abstracting the underlying implementation and only exposing the objects or actions the web or software developer may need. API Full Form is the Application Program Interface, which makes the communication between programs, operating systems, and application programs.
Usage of API:
API can be used on multiple platforms and multiple purposes. In the following, some of the usages of API are described.
Libraries and Framework
In a library, especially a software data library, a program the API describes and prescribes the “expected behavior” (a specification). In contrast, the library is an “actual implementation” of this set of rules.
A single API (Full Form Application Program Interface) can have multiple implementations (or none, being abstract) in the form of different libraries and functions that share the same programming interface.
An API can also be related to a software framework: a framework can be based on several shared libraries used in implementing several other APIs.
But unlike the regular use of an API, the access to the behavior developed into the framework is negotiated by extending its content with new classes plugged together into the framework itself.
The ‘program flow of control’ can be entirely out of the control of the caller and in the hands of the framework or similar kind of mechanisms.
Operating Systems:
An API can be found working as the most crucial bridge between the application software and the operating system.
Many operating systems like POSIX, Linux, and Windows use dedicated API to ensure that the older version of the application program can run on newer versions of operating systems. Win32 is one of the most common examples of this feature.
