Can you withdraw real money from Bitcoin?

Excuse me, I was wondering if you could possibly clarify something for me about Bitcoin. I've heard a lot about it, but I'm still a bit unclear on the concept of withdrawing real money from it. So, my question is, can you actually withdraw real money from Bitcoin, or is it just a digital currency that's meant to be used for transactions online? And if it is possible to withdraw real money, how does that process work? I'd really appreciate your help in understanding this.
