I try to explain it (with non technical words and my awful english).
An operating system - OS for short - is a set of (complicated) istructions and I don't say more because, for me, it is difficult to explain even in Italian.
The difference of 64 bit is to connect to the Numerical Analysis and I don't know it perfectly. I can say that, in a 64 bit processor, the 64-bit OS can work with the full power (calculus power I mean) with more speed. I note the difference in the background work of the OS (like system processes) and in programs built for 64 bit architecture respect to the one for 32 bit.
So I have a 64 bit processor in which is istalled win 7 32 bit. For a month I had win 7 64 bit and it was very faster respect to the actual OS I have: boot time, office programs (word, excel, power point, matlab...), media editors, ecc...
I didn't note a big difference with games except for the video card that with the 64 bit drivers offers a better quality of image.

I try windows 8 (customer review) in virtualbox and I note that - in appearance - is totally different from windows 7. But I can't express a word because my trials are poor.
In my opinion souds better "you're right".)
That is the "normal" short answer that we are taught at school, but answering saying "you're right" or just "yes" it's absolutely correct and even more informal and "natural": in two weeks' time I spent in London I hardly ever heard the "normal" one 
) and, after having tried to run Ubuntu without success, I'm now thinking of Windows 7. I don't take into account win 8 for the reasons I said before (even if I haven't tried it yet). My PC is a bit old (5 years), but the processor works still fine and I provided it with 4 GB of RAM so win 7 should run on it. I'll have to check if my AMD supports 64 bit architecture...
