Want to put 32 bit OS on a 64 bit system

[KABIRA]

Can some one tell me is there any difference between a 32 bit and 64 bit system and OS ? Is it possible to put a 32bit OS on a 64 bit system ?

System requirements

32-bit : 1-gigahertz (GHz) 32-bit (x86) processor or 64-bit (x64) processor, 512 MB of RAM.

64-bit versions : 1-GHz 64-bit (x64) processor, 1 GB of RAM (4 GB recommended).

You can put a 32bit OS on a 64 bit system. about difference A 32-bit version of Windows Vista can access up to 4 GB of RAM and A 64-bit version of Windows Vista can access from 1 GB of RAM to more than 128 GB of RAM.

The difference is 32 bits. Make sure you have a 64 bit processor and all the drivers you need or 64 bit might be a pain.
