job
     
         All the activities involved in completing
        any project on a computer from start to finish.  A job may
        involve several processes and several programs.
     
        This term is rather old fashioned and harks back to the days
        of {batch} processing where a user would submit his job as a
        deck of {punched card}s which would typically include {source
        code} interspersed with {job control language} instructions to
        guide the various phases of the job such as compilation,
        linking, execution and printing.
