An API (Application Programming Interface) is a set of code that allows two software programs to communicate with each other. APIs are a critical component of web development and programming. They provide a way for different applications and systems to communicate with each other, exchanging data and enabling functionalities.
APIs are a software intermediary that allows two applications to talk to each other. They define how a developer should request services from an operating system (OS) or other application, and expose data within different contexts and across multiple channels.
API:- Application Programming Interface
CGI:- Common Gateway Interface
COMMON GATEWAY INTERFACE (CGI)
refers to the program that accepts requests on behalf of the server and operates as an interface.
WEB SERVICES is a program that provides CGI functionality. WEB SERVER is the system that runs web services.
As a result, Apache is used as a web server in this case. To configure a web server, Apache provides the program httpd.
WEB PAGE:- The page that shows the code.
WEB APP:- The page that runs code.
WEB CLIENT:- Chrome/ Firefox etc. are known as web clients.
Also, in this task, we use Python as a language so Python is known as SERVER-SIDE LANGUAGE.
Application Programming Interface (API) :
Now, let’s look into API:-
In the URL, we offer a PROGRAMME name so that the client may interact with the server via an INTERFACE and run an APPLICATION generally known as API.
CGI assists the client in entering the server, and once inside, it is up to the API to determine which program to run.
Hopefully, this was useful.
