Backend
The part of a website or application that runs on the server.
Definition
The part of a website or application that runs on the server. It handles business logic, processes data, communicates with databases, and sends information back to the frontend. Users never see the backend directly.
Example
When you search on Google, the frontend sends your query to the backend. The backend searches through billions of indexed pages, ranks the results, and sends them back to your browser for display.
