Default What is Noise?

Hi all,
I am shooting with a D100 at ISO 1600 in a hockey rink with no flash. I know I have noise, but what is noise? How can I determine that my image is noisy and not just sharp?

Here's an image: http://www.emrep.com/Temp/113003_0027.jpg

Where is the noise here?? or does the image just lack sharpness?

Thanks
Eric

I'm not an expert, but to my eye the photo looks "soft" or not quite pin sharp as opposed to being out of focus. I can't discern any noise (rather akin to grain in film photography), but maybe someone with more expertise in these matters can give you better information.
