Explanation:

Note:
Providing a UNIX Group Name

If you are installing a product on a UNIX system, the Installer will also prompt you to provide the
name of the group which should own the base directory.
You must choose a UNIX group name which will have permissions to update, install, and deinstall
Oracle software. Members of this group must have write permissions to the base directory chosen.
Only users who belong to this group are able to install or deinstall software on this machine.
