API is the short version of the Application Programming Interface (API). The Application Programming Interface is an interface that provides computers, libraries, or applications for other services to provide services or exchange for data.
The main function of an API application is to describe how a computer application or a software developer describes the accessibility functions of different functions of those applications. For this, it is not necessary to access the source code of the application’s function or to get a full explanation of the source code. The API is an abstract concept since it is an interface.
Computer programmers often use operating system APIs to distribute memory and access files. Different systems and applications allow APIs. Among them, graphics systems, databases, networks, web services and even computer games are notable.
