What's the difference between Linux operating systems?

[xudeng]

Linux has a lot of operating systems, I'm not even going to bother to list them. I was wondering, it there a difference between them? Does each type of Linux operating system hold a specific purpose? For example, Red Hat holds a different functionality to Ubuntu, or something like that.

The answer is clear I think - each type has it own pros and cons as well as different features that can provide with different opportunities.
