Permission:
Computer holds many files and folders. Each file and folder has an authorized creator and user. Not all users are allowed to access files, folders, and contents in files and folders. For every object in files and folders, there are different properties.
Permission is one of the properties of object. Only the users who have privilege can use and perform some actions. If read only permission is given to user, then user is allowed only to read the contents of file but would not allowed to edit or change contents of file or folder.
File creator or network administrator or system admin defines the file and folder permissions. If a word file is given (read/write) permission, then user can read and update contents of file and save the file.
