Answer: Every file and directory in Linux are assigned three types of owners namely 'User', 'Group', and 'Others'.
The three kinds of permissions defined for all the three owners are:
- Read: This permission allows you to open and read the file as well as list the contents of the directory.
- Write: This permission allows you to modify the contents of the file as well as allows adding, removing and renaming files stored in the directories.
- Execute: Users can access and run the file in the directory. You cannot run a file unless the execute permission is set.
