you can't download Unix. i think. *snickers*
UNIX developed at bell labs in 1969 was the [censored] child of an OS that almost never happened called
MULTIX(Multiplexed Information and Computing Service) or something like that. Anyway, Bell(back then Ma bell) and many of the other vendors pulled out saying it would never work, or it isn't worth the money. You get the idea. Multics was worked on from 1965 to 1969 when Bell labs withdrew support.
Bell Labs still had all thier code and notes on the project. Bell labs would not fund any similar projects because this last one failed to yeild profit and results. A small group of researchers at bell labs however saw the potential of Multics and beged for equipment to develop thier own OS. This allways ended up the same. No funding. The breakthrough came when Ken Thompson found a little-used PDP-7. This relatively small, inexpensive computer with a video terminal became the first computer to run UNIX. Ken Thompson wrote the initial operating system while his wife was on vacation for a month � allocating a week each to operating system, a command-line shell, a text editor to write programs with, and a PDP-7 assembler to turn the files created with the text editor into machine code. Interestingly, it wouldn't be until 1970 that the name "UNIX", a pun on "Multics", was coined.
Some of the above is copy and paste from here
http://www.macos.utah.edu/Documentation/MacOSXClasses/macosxone/unix.html In 1975 Ken Thompson, Bell Labs... The same man gave birth to UNIX took leave to teach at UC Berkeley. By 1977 Ken had had his students, 2 of them actualy re-write UNIX and make improvements. Not sure, but I belive not 1 line of code was the same. This becams 1BSD (Berkeley system distribution). See BSD logo below
HTML and the first webbrowsers can be tied to a UNIX OS as well.
Till eventualy we come to a *NIX clone version called Minx. A young lad by the name of Linus was using the OS MINIX. He had problems with certain things and wrote the creators and was told screw you this is our OS. Not realy, but they refused to make his changes. So Linus started making his out UNIX like kernnel. He went in his basement and worked for a realy long time with out a break. At least an hour at a time. When he rose up to the world again he had given birth to the LINUX kernnel. He later teamed up the GNU guys and they released the GNU/Linux OS. open source/free software was born, or had a really big shove in the right direction.
Here is the dael guy.
UNIX - Not free. Actualy very expensive. Usally requires special computers to run it. Who owns it, well many people. That is another ball of string to untangle. Some true UNIX systems are
AIX
AT&T UNIX v5r5
Solaris
BSD - Some are free, Some are not. The BSD license is not the same as the LINUX license. It allows vendors for charge for thier version of the OS. Many will run on your PC. But not in windows XP. This is it's own opperating system. (I know there are ways guys but let him crawl first(VMWARE)).
Some versions are
Open BSD
Free BSD
Net BSD
BSDi
Linux - Linux kernnel and the GNU software(anything releasd under the GPL License).
some versions are
Red Hat
Slackware(the first and some would say still the best)
Mandrake
Debian
Gentoo
and sooooo many more.
So quick wrap up. All these systems will behave very similar. LINUX, and BSD were made to be exactly like UNIX but better. They are all POSIX compliant. That all have similar shells. So what is the difference? Some you can see the code. Some you can run on PC's. Some you do not have to pay for. Some will allow you to change you code anyway you want and encourage you to give that change away.
LINUX
BSD
UNIX
3 different things that are very much alike.
