UNIX is an operating system developed around 1969 from Bell Labs according
to:

Since then many clones and reimplementations of very similar Operating
systems have
been released. Most of them were developed by some company and sold running
on their hardware (HP unix, IBM 's AIX, Dec OSF, Cray unicos, ....).
</BLOCKQUOTE>
<BLOCKQUOTE>
Another one of them is Linux -- a Unix kernel rewrite started as a project
by Linus
Torvalds with the remarkable difference that the Linux kernel was and is
free --
free in the sense that everybody has access to the source and is free to
redistribute it as well as modifying it.
</BLOCKQUOTE>
<BLOCKQUOTE>
Linus' work was made possible by another project: GNU. See below.

I see people say that specific line so often it rates as a myth.
Actually the GNU project had nothing to do with his kernel; I believe his
earliest kernels weren't even under GPL; beyond that, not all GPL'd
applications are part of the GNU project, in fact I dare say most of them
aren't, esp. since there's more of them every day. See "distribution"
below for what really needed GNU tools to get going.

loosely the core part of the operating system which handles all the
hardware and
resources of a computer.
</BLOCKQUOTE>
<BLOCKQUOTE>
The kernel also is code which has more or less free access to memory and
hardware
in contrast to "user space" where the hardware access has to go through
the method
the kernel provides.

</BLOCKQUOTE>
<BLOCKQUOTE>
This had all the tools like compilers which are necessary to buid an
operating system as well as all the little commandline programs which
make the Linux kernel
to a Unix like operating system (what would one do without commands like
ls, mv, ps or sh, bash, ....).

Hardly <EM>all</EM> the tools; about as many of the tools in a typical system
are under BSDish or other free licenses. If you measure by bits instead
of how many packages, X is fairly heavyweight and remains under an MIT
license. A lot of Linux users use X, many even consider it a day to
day necessity.

Among other things a real GNU project
utility author would have transferred his, her, or their copyrights to
FSF, something which not everyone feels inclined to do, by a long shot.

Aehm.... operating system?
Combination of a kernel handling the hardware access along with a program
collection which allows all basic file operations, compiling,....
GNU/Linux would be one.

Distribution
</BLOCKQUOTE>
<BLOCKQUOTE>
"Linux" is only the kernel of an operating system. Along with it one needs
GNU
tools and a lot of other free, open source or commercial software for a
productive computer system.
</BLOCKQUOTE>
<BLOCKQUOTE>
Companies evolved which pack ready made systems including a kernel and a
selection
of tools and programs acording to their distribution philosophy.
Even if the software and kernel itself is free and freely redistributable
the
companies can charge for the work to arrange everything so one can choose
what to
install and make sure that everything will work together. Also you will
get about 1
to 7 CD and a handbook from most of them.

Hardly the first, but the best maintained survivor from the old days.
Hit the net looking for the keywords "Yggdrasil" or "Soft Landing Systems"
or even see the earliest issues of <EM>Linux Journal</EM> (SSC's magazine) for
some <EM>really</EM> early distributions.

Many distros can easily be found at their .com or .org domain. Linux
Weekly News (<a href="http://lwn.net/">LWN</a>) has a really nice sidebar leading to lots of distros,
many especially tuned for some special purpose.
