From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I think the POSIX standard only has one root user, however many users can have root privileges.

So it's probably a trick question, however any user even without privilege can make create a file which others can't, read even the root itself I think not sure though.

What do you mean by other roots? Isn't root only one?

There is only one root user. Other users may have root access though. Any user can create files only readable by them, but root user can override all of them, change password of any user etc. For a user having root access, they can do all sorts of things root user does
