    Which one of the following DOS commands sends contents

    of the screen to an output device?
    A BREAK Correct Answer Incorrect Answer
    B ECHO Correct Answer Incorrect Answer
    C MORE Correct Answer Incorrect Answer
    D ASSIGN Correct Answer Incorrect Answer

    Solution

    The ECHO command prints its own arguments back out to the DOS equivalent of the  standard output stream. (Hence the name, ECHO) Usually, this means directly to the screen, but the output of  echo can be redirected, like any other command, to files or devices.
