Back End (Computing Architecture)

The back end of a computer system or network refers to the concealed portion that is not visible on the user’s screen, contrasting with the front end. Back-end developers employ programming languages like JavaScript, C, C++, and WebAssembly (WASM), alongside other tools, to construct the back end or data access layer (DAL) of a computer system. Conversely, the front end denotes the user-interaction section of a website or system displayed on the screen, commonly known as the graphical user interface (GUI).
