In a university environment how might the user access classes “owner,”“group,”“specified user,” and “public” be used to control access to files? Consider the use of the computer system for administrative as well as academic computing. Consider also its use in support of grant research as well as in academic courses.

What will be an ideal response?

The owner class would be useful for private files on the network, such as a student’s
programming assignment. The group access class would be useful for lecture slides or homework
assignments given out to the students of a certain class. The specified user class would
be good for returning homework assignments to students.The public class would be good for
making announcements or posting research papers, and so on.
