Welcome to the forums,
Linux is the core [Kernel] of the operating system commonly called Linux, developed by Linus Torvalds,
"Who owns the copyright on Linux? Lots of people. Nearly
everyone who has contributed code to Linux reserved his own
copyright. Some of that work was done for hire and therefore
the employing corporations own the copyright. Linus Torvalds
is the most visible copyright owner, but he hold copyright on
a very small part of Linux."
Linux as its commonly referred to is a distribution built and developed around the Kernel consisting of the kernel, a collection of applications [Windows users call them programs] and a GUI [user interface] of which there are thousands of variants including over 500 desktop versions.
