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.
