API (Application Program Interface)
An API is a group of protocols, functions, and commands for constructing software applications. It’s an acronym for Application Program Interface; a software intermediary that helps two different programs to communicate with each other. They specify ways of communicating between different elements on different computers. The main goal is to provide a software tool that can be used by programmers and system administrators to create and run software programs.
An application programming interface is defined in terms of its rules and specifications that allow a program to use a number of different types of data formats and transfer information between software and hardware components. It’s generally used to define communication protocols and data representation. The term ‘API’ came about because of the fact that this was the first set of data structures ever created by any kind of computer science (including language design). Basically, it defines how two or more systems can work together when they are working over a network, using the same program, to exchange information.
So, now you know what an application programming interface is and why building software using it is essential. If you’re reading this article, then you have already taken the first crucial step towards making your next software program communicate effectively with its users. In addition, now you have a good idea of what an application program interface actually is and why it’s necessary to use it whenever you’re designing a new piece of software.
