32 and 64 bitI want a learning moment

I don't understand what you mean by:

AMD64 is 64-bit CAPABLE

Does this mean that even though you said I probably have a 32 bit that the above quotes means I can run 64 bit programs? I read some of the links about the differences between the two & they state that 32 can not run anything that is for a 64 Bit but that 64 Bit can run things made for 32 bit. I am thoroughly confused.:confused:
Thanks,

A 32-bit OS cannot run 64-bit apps.

No. I meant the processor is capable of running 64-bit OSes. If you have a 32-bit OS, you CANNOT run 64-bit applications.

I know I must sound ignorant, but what is a 64-bit OSes
Thanks,

64-bit Operating System such as XP x64 or Vista x64.
