What is Back End (Computing Architecture)?

The back end of a computer system or network refers to the portion of the system that is not displayed on the user's screen, or front end. Back-end developers normally make use of various programming languages like JavaScript, C, C++, and WebAssembly (WASM) along with other tools to create the back end, or data access layer (DAL), of a computer system. In contrast, the front end is the portion of the website or system that the user interacts with on the screen, also commonly known as the screen or graphical user interface (GUI).
