linux is actually just the kernel. when you buy a "linux" cd or download it your downloading the kernel plus all of the other open source applications that make it an operating system. the only actual thing that you could call linux is the kernel itself. the kernel operates behind the scenes and dictates how you computer handles resources, hardware, etc. thats why most people like to call "linux", "gnu/linux" because it consists of gnu programs.

unix does not use the linux kernel. that is why it is called "unix". also, linux is a derivative of unix. it was built from unix and is called a "unix clone" but ever since the media has taken ahold of it most people have forgotten

for a greater lesson go to gnu.org and read all about it.

read first, ask second.

read first, ask second is a derivative of search first, ask second. ;)

unix is copyrighted.
linux is a unix equivalent; and since Caldera bought unix, is unix linux?

eerrrr...no.

Caladera did not buy unix, they stated to sell it. Basicly its like linux. You have your kernel, and then you have your software distrobutions built up around that kernel. Except that Unix is expensive.

Someone correct me if I'm wrong.

Actually they purchased sco unix and now have the following products.

OpenLinux Server
Open UNIX 8
OpenLinux eServer 2.3
UnixWare 7
SCO OpenServer
OpenLinux Application Server with Tarantella
OpenLinux Workstation 3.1
OpenLinux eDesktop 2.4

They've merged the best of both worlds. Unix and Linux

I was at the Toronto Comdex a few months ago and Caldera was the only Unix/Linux company there. Was their booth ever busy.

I've been using Caldera since I started a couple of years ago with OpenLinux 2.2. Now that I've upgraded to OpenLinux Workstation 3.1 both at work and at home, I couldn't be happier. One fine distro and everything works. Luckily Caldera compiles and builds all included applications on their base so as to ensure everything will work.

In order to be a UNIX, you have to get licensed by The Open Group (http://www.opengroup.org). In order to get licensed, you have to pay a certain fee and conform to a certain set of standards. Linux conforms to (nearly?) all of these standards, but has no real reason to pony up the money for licensing it.
