API\u00a0<\/span>stands for Application Programming Interface. Of course, sometimes it is better to call it “software programming interface”. APIs are responsible for communicating between two executable codes in different locations. In other words, an application programming interface is a way for software to talk to each other.<\/span><\/p>In another definition, it can be said that APIs <\/b>are an abstract layer between two executable programs that provide specific accesses and connections from the server to the client. In general, in computer science, if you face a problem that is complicated to solve, it is enough to use abstraction layers and reduce the complexity.<\/span><\/p>Think of abstraction layers as columns, so that the parts above the abstraction layer depend on the components below it. The abstraction layer makes it possible to make rules that work without considering the details of the underlying layers.<\/span><\/p>An example of an abstraction layer is the ISA (Instruction Set Architecture) layer in computer architecture, which makes programmers write their programs and manage hardware without considering the hardware implementation details by using the assembly language of that architecture.<\/span><\/p>Obviously, the APIs themselves are implemented by programming code. One of the goals of APIs is to prevent the complexity of implementing some algorithms. For example, the algorithms of decision support systems are complex and their implementation requires a certain level of knowledge; But in Bigpro1, it is possible to use APIs of the decision support system. When we send a request to an application through an\u00a0API<\/span>, we are not supposed to know what functions are being called in that application and how they work, we just need to reach our main goal as quickly as possible.<\/span><\/p>You probably assume that APIs are always used in websites and online applications; But this thinking is wrong. We will discuss this further.<\/span><\/p>\u00a0<\/span><\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
