Command-Driven Interface (CDI)
The command driven interface or CDI, is navigated via the keyboard. It can display and accept as input, ASCII text characters like A-Z, a-z, 0-9, !#*$&@^, etc., but does not handle graphics. You communicate with the OS by typing commands like "copy A:*.* B:" or "dir". It communicates back to you by displaying the results of your command, generally directly below the area of the screen in which you typed the command.
What CompTIA calls the CDI is more usually referred to in the real world as a CLI, or command-line interface. But as far as the A+ certification goes, they want you to call the non-GUI user interface, a CDI.
