On a network, users can have different levels of access to control what they can view, edit, and delete. Set-up correctly, user access levels can prevent lower level employees accessing sensitive information, or prevent users accidentally deleting data. In School we use access levels to protect data. Students can only access and edit their own files, Teachers can access and edit student files, their own files, and edit files on shared drives. Without access levels anyone within a school would be able to access any files on the network.
