System V and BSD

[lad24mx]

Can anybody explain to me the difference between System V and BSD?

I know that distros such as Red Hat and SuSE are based on system V and I believe Debian and the upcoming Apple X are based on the BSD design.
Why the difference?

Please enlighten me guys.

Later.

I totally stole this from a webpage and it's formatted, so I'm putting it in code tags:
