While some file managers implement file sharing by allowing several users to access a single copy of a file at the same time, other implement file sharing by providing one copy of the file to each user. Fill in the following table you may expand it if necessary (if your answer is longer than several sentences, although it probably shouldnt be). In any case, your answers MUST be placed in the table. This question is worth 12% of the assignment.
