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.

Can you explain what image based OS means?
The core operating system is a single read-only file (ROM, as in custom ROM on Android) and all the user files and customizations are on a different partition or such. Since the core system is fixed you can just swap it with a newer ROM when updating (and also go back to the old one if the update fails somehow.).
