API-Definition: API, was ist das?

According to the API definition, the word is an abbreviation for "Application Programming Interface" - i.e. a programming interface that enables other programs to connect to the software system. According to the API definition, the connection to the interface takes place at source code level. APIs are used in many applications because they allow you to work with the local data of a device without having to address it directly. According to the API wiki, these are called web APIs in the web environment. The use of code modules together with APIs makes programs less error-prone and easier to maintain. The API meaning is: Information can be exchanged in a standardized way between the application and individual program parts via a programming interface, whereby the transfer of data and commands is structured according to a previously defined syntax. The short API meaning is therefore also: The modularization of programming by means of an API interface simplifies it. This is because the individual program parts connected via an API fulfil specific functions and are clearly separated from the rest of the application. According to the API declaration, communication only takes place via the precisely specified interface. This allows external developers to develop software applications for the corresponding operating system via API access. Cloud services and cloud computing are contributing to the increased importance of APIs, as they enable the API integration of cloud services into local systems or other cloud services. On an API course, you will deal with the API definition and its functions.
