NI SCXI-1000 simplifies the underlying implementation of programming extraction

The term API usually refers to web APIs,[2] which allow the Internet to be communicated between connected computers. There are also apis for programming languages, software libraries, computer operating systems, and computer hardware. API originated in the 1940s, although the term did not emerge until the 1960s and 1970s. Recent advances in apis have led to microservices, which are loosely coupled services accessed through a public API. [3]

When building an application, the API simplifies programmatically extracting the underlying implementation by exposing only the objects or actions that the developer needs. While a graphical interface email client for use might provide the user with a button that performs all the steps of getting and highlighting a new email, a file API input/output might give the developer a function that copies files from one location to another without requiring the developer to understand what is happening behind the scenes in the file system. [4]

The term application interface originally described only an interface for end-user oriented programs, called applications. This origin is still reflected in the name Application Programming Interface. Today, the term is broader and includes utility software and even hardware interfaces. [6
