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.

thank you! I think this is what needed to explore
It is not my level to edit these things, I'm just Linux newbie exploring the possibilities.
But I still can't wrap my head over dd not being able to wipe a storage device out, despite being described as a "low level tool that can write zeroes to targets" in the discussion I viewed online.
The bios isn't like a regular storage device presented to the kernel for mounting.
Dd can’t overwrite a burned cdr either. If the thing you wanna mess with is read only there’s no way to use it as a dd of.
but CD-R aren't rewrite_able because of their physical property not because protected
that's true, but in both cases the ability to write data simply isn't there.
