Hi,

I'll try to help with this one.

The kiloBytes is measuring how much information has been 'extracted' from your site by a visitor. Most ISPs give you a limit to the bandwidth that you can use each month. In other words, only so much information can be downloaded from your website. Basically, your KB must not exceed you bandwidth. (so far it's never happened to me)

Your sites, may be referring to the sites who have refered a visitor to you, for example, if I had a link on my site to you, and someone followed it, I would be in your stats as a referer.

Hope this helps
