Node
Nodes are probably the hardest Drupal concept to grasp but they are really  
quite simple. Almost all content in Drupal is stored as a node. When  
people refer to "a node" all they mean is a piece of content within  
Drupal, it could be a poll, a story, a book page an image etc.

I doubt this being correct. Is a 'product' in a webshop content for  
example? A group of users as in og.module? No. We need something better  
here. Here are my two cents on the definition -- note that I am a math  
freak. Node is among other things is a synonym for vertex in graph theory.  
I can imagine two types of graphs in this context: one is that nodes are  
built by node type modules and nodeapi stuff and these cross, we find a  
node. Also, taxonomy terms can be thought of edges between nodes (that  
taxonomy also has hierarchy is irrevelant this context).

In layman terms, node is something where stuff comes together. ..
