...and they say there is no such thing as a stupid question; this certainly gets close...
Both are powerful (in the right hands). This should be apparent if:
- You understand much about Linux/Unix. It would be difficult to come up witha Unix style system that didn't have power in one sense or another, although for, eg, embedded systems, that would be quite a different sort of power from that appropriate for the data centre.
- You understand them organisationally (i.e., that they have a common origin)
To discuss this any further, there would clearly need to be some kind of definition of what is meant here by computer power and that seems to have been overlooked in your question.
...it would be easy to get the impression you were just here to advertise your blog
If this is genuinely a way to attract attention to your blog, you might ask youself what people would expect after a question like this? Something badly written with a poor grasp of the fundamentals?
Well, at least you won't be letting visitors to your blog down, and that's important, I suppose.
