64 Bit system 32 bit program

[Wolfi83]

Hey,

I have a 64-bit system with lib32 libraries and a 32-bit program. Can the system use more than 4 GB RAM for this program?

No, its a limitation in address space compared to 64bit.

Very often, when referring to the word size of a modern computer, one is also describing the size of address space on that computer. For instance, a computer said to be "32-bit" also usually allows 32-bit memory addresses]
