What's the difference beetween kernel, and kernel-smp?

I just installed fedora on my new computer, and in the grub there are 2 fedora boot points, the first uses the kernel, the other uses the kernel-smp. Waht's the difference between the two kernels?

Extract from http://www.webopedia.com/TERM/S/SMP.html

(1) Short for Symmetric Multiprocessing, a computer architecture that provides fast performance by making multiple CPUs available to complete individual processes simultaneously (multiprocessing). Unlike asymmetrical processing, any idle processor can be assigned any task, and additional CPUs can be added to improve performance and handle increased loads. A variety of specialized operating systems and hardware arrangements are available to support SMP. Specific applications can benefit from SMP if the code allows multithreading.
So I think that processors with HT can benefit from this performance boost.
The other one, w/o the smp ending, is the standard kernel, without the HT support, I think.

FYI, I am running FC4 with an SMP kernel on this P4-3.2GHz (HT-enabled) computer. It has been working pretty well.
