foreground
     
        (Unix) On a {time-sharing} system, a task executing in
        foreground is one able to accept input from and return output
        to the user in contrast to one running in the {background}.
        Nowadays this term is primarily associated with {Unix}, but it
        appears first to have been used in this sense on {OS/360}.
        Normally, there is only one foreground task per terminal (or
        terminal window).  Having multiple processes simultaneously
        reading the keyboard is confusing.
