Definition[edit | edit source]
A text user interface (TUI) (also called textual user interface or terminal user interface) is a text-based user interface. TUIs are different from command-line interfaces in that, like GUIs, they use the entire screen area and do not necessarily provide line-by-line output. However, TUIs only use text and symbols available on a typical text terminal, while GUIs typically use high-resolution graphics terminals.
