What is Backend?
It is the part of an application that is not visible to the user, where data is processed and which runs on the server.
Overview
The buttons or menus you see when you enter a website are the frontend. The backend is the part that does all the heavy lifting in the background, such as verifying your passwords, retrieving information from the database, or processing payments. The user only sees the result, while the backend is the kitchen that prepares this result.
How it works
The code running on the server receives incoming requests, communicates with the database, and after performing the necessary logical operations, sends the result back to the user.
Where it is used
It is found in all modern web applications, in the background of mobile applications, and in API systems.
Commonly confused with
It can be confused with the frontend; the frontend interacts with you, while the backend does the work.
Frequently asked questions
