My instructor posed this question to me, and I'm having a little trouble getting a good answer.  Most pages that I find that seem to be related are about 15 pages long full of a lot of side info that I don't need.  Perhaps someone can offer some insight, maybe a good site to look at?  I don't just want someone to answer it for me, because then how will I learn.  I just need a little direction....  Anyways, here is the discussion board question.

Most computers today follow a simple architecture (stored program) that has been around for dozens of years. What is this architecture called? Why? What's another and why is it different?

Now I did find something about a Von Neumann architecture, but nothing that will help me define it.  Anyone?

Thanks much
