PB and Jelly? or Jam? or Preserves?

I've always wondered what the difference between jelly, jam, and preserves. Thanks to Food Network, I've learned the following about peanut butter's best bud:

Jelly is made from fruit juice.
Jam is made from fruit solids.
Preserves are made from the entire fruit.

Now don't ask me if I think they taste different, because personally, I think they taste pretty much the same. However, I will say I enjoy actual fruit pieces in my spread.
