Back-end

Back-end is the part of web development that deals with processing and managing data on the server side of web applications. It consists of code written in various languages, most commonly PHP, Python or JavaScript. Back-end developers deal with server-side logic programming, API design, security and other technical aspects of web applications. The back-end is important to the proper functioning of web applications because it allows for user access control, communication between different parts of the application, and data processing and storage.
