The Free On-line Dictionary of Computing (30 December 2018):

interactive

    A term describing a program whose input and
   output are interleaved, like a conversation, allowing the
   user's input to depend on earlier output from the same run.

   The interaction with the user is usually conducted through
   either a text-based interface or a graphical user interface.
   Other kinds of interface, e.g. using speech recognition
   and/or speech synthesis, are also possible.

   This is in contrast to batch processing where all the input
   is prepared before the program runs and so cannot depend on
   the program's output.
