api has many meanings, let’s learn about it below.

api (Application Programming Interface)

API (Application Programming Interface, Application Programming Interface) are some predefined functions. It is to provide applications and developers with the ability to access a set of routines based on a piece of software or hardware without having to access the source code or understand the details of the internal working mechanism

The main purpose of the API is to provide applications and developers with The ability to access a set of routines without having to access the source code or understand the details of the inner workings. Software that provides the functionality defined by an API is called an implementation of this API. API is an interface, so it is an abstraction.

# The operating system's API can be used to allocate memory or access files. Many systems and applications provide API interfaces and implementations, such as graphics systems, databases, networks, Web services, and even some games.

A set of APIs is often part of a software development kit (SDK). SDK can also include other tools or as for hardware, the two terms are not completely synonymous.

API has many different designs. Interfaces for fast execution usually include functions, constants, variables and data structures. There are other ways, such as through an interpreter, or by providing an abstraction layer to obscure information related to the API implementation, ensuring that the code using the API does not need to be changed to adapt to implementation changes.

API is the application programming interface. It is a set of functions that can be used to operate a component, application, or operating system. Typically, an API consists of one or more DLLs that provide some special functionality.

A DLL is a file that contains functions that can be called by any application running under Microsoft® Windows®. At run time, functions in a DLL are dynamically linked into the application that calls it. No matter how many applications call a function in a DLL, there is only one file on disk containing that function, and the DLL is only created when it is loaded into memory.

The API you hear about most is probably the Windows API, which includes the various DLLs that make up the Windows operating system. Every Windows application interacts with Windows APIs, either directly or indirectly. The Windows API ensures that all applications running under Windows behave in a consistent manner.

API (Advertising Evaluation)

api (Ameritest Performance Index) is an indicator value that combines attention, brand connection and persuasion It is calculated through complex formulas based on the values ​​of three factors, and is linked to the average market performance of these indicators. This can be simply understood as: API = Attention To make an advertisement more effective, first of all, our audience must notice it, and in order to attract the audience's high-quality attention, the advertisement must be touching and engaging

Brand connection:

• Another important factor related to the success of advertising is brand connection. Without enough brand connection, no matter how good-looking the commercial is, it will be ineffective. Maybe the ad does the job of promoting the product, but, worse, it may promote a competitor rather than ourselves.

Persuasiveness (Purchase Motivation):

• Finally, advertising must be persuasive. The information conveyed must make the audience feel that it is highly relevant and convincing to the brand product, and prompt them to purchase, or at least make them want to learn more.

• API (American Press Association)

  Full English name: air position indicator.
