How do I check my whether my Ubuntu is 32-bit or 64-bit and whether or not it is using full RAM? I'm concerned that because my system is 32-bit it isn't using the maximum OS-supported RAM. It says my PC has 8GB RAM, but how do I verify it is using or detecting this as 8GB RAM?

Regarding Sotanaht's answer: the System Tab shows Release 11.04 (natty), Kernel linux 2.6.38-11-generic-pae, Gnome 2.32.1 .

Follow up:

After finding my answer. Because I have 8GB hardware RAM, I don't want to be restricted to 4GB RAM, therefore removing my 32-bit Ubuntu 11.04, and downloading 64-bit Ubuntu 11.04 (so that my applications can utilize full hardware RAM too, specially for 3D animation rendering, image processing, video editing)

PAE means your kernel is 32-bit but it's configured to use Physical Address Extension so the whole OS can use all your physical memory. The limitation of PAE, however, is that no application alone can use more than 4Gb of memory.

See the wikipedia article for more technical details
