64-bit Linux OS and 32-bit application
 

Hi,

I am new to this forum and need help from the Linux gurus over here.
If we have 64-bit SUSE Linux OS and 32-bit application running on a board which has 30 GB RAM, it is for sure that the OS can access the whole 30 GB RAM. But, the question is can the 32-bit application access the whole 30 GB RAM or only 4 GB of RAM? I guess only 4 GB. Could any one of you have a quick answer and the theory behind the answer?

If only ONE 32-bit application is running on a 64-bit SUSE OS on a board having 30 GB RAM, application can use 4 GB RAM and 26 GB RAM will be a waste and not used at all ???

Thanks & Regards,
Ramesh.
