Hm. I don't really know how an abacus works. I only have a vague idea,
which is (or was): you move those beads to remind you of numbers. :-)
So I said: well, that's just RAM.
Anyway, I could go out on the web to find out how it works, but if you
feel like, why not explain it to a slow person?

Indeed. But we can imagine a huge one?
