Definition
The backend refers to the server-side part of a web application or website that is not visible to users. It is responsible for managing the database, server, and application logic, processing requests from the frontend, and sending data to be displayed to users.
Function
The main function of the backend is to handle the data exchange between the server and the client (frontend). It processes user inputs, performs calculations, retrieves and stores data in databases, and ensures that the application runs smoothly and efficiently. The backend typically involves server programming languages (such as PHP, Python, Ruby, or Node.js), database management systems (like MySQL or MongoDB), and server architecture to support various functionalities of a web application.
