No worries :) ok, almost any recent,decent computer can run 64 bit, ie in last 4 years or less.

32 and 64 bit, right, try and explain this, it comes form binary mathematics. and reffers to how "wide" or "Big" the amount of data the software can access at one time (sort of). Now, sicne i'ts biinary you have a sort of logarithmic progression.
it also limits how much RAM can be used.
The old Spectrum and CommodoreC64 were 8 bit computers, the Amiga was a 16 bit ocmputer and pentiums 32 bit. You can see the progression in power. 32 bit computers can only use a max of 2 gigs of RAM (or 3,5 with a trick)
When you get to a 64 bit computer, it can use...17 billion giigabytes!! but no motherboard in a PC can use more than 32 gigs at moment and most can only use 4 or 8.

this icnrease has profoudn effects, Vue on a 64 bti system I got built to my specs (quad core CPU, 8 gig RAM, vista 64 bit, now windows7 64 bit), completely blows the a** out of my 4 GHz Pentium 4 with WIndos XP 32 bit. Renders about 10 times faster and I cna throw vaslty more things into a scene before it starts to use up a lot of memory
if you look at my gallery you'll see how I can use many Poser and other models in one scene at the same time.

In WIndows 7, to see if it's 32 or 64 bit that's installed, go to START --> CONTROL PANEL __>SYSTEM AND SECURITY -->VIEW AMOUNT OF RAM AND PROCESSOR SPEED
the system type tells you 32 or 64 bit
