Ok tried to get info on the node on my own, I failed going to admit to being the newb here.

I know the general meaning of "node" but I'm not sure how it ties in to P2P and bitcoins.
I understand how mining works you just completely lost me on node.

Is that something I'd want to do, what are the benefits / costs etc?
If it generally goes by another name and I can research it on my own I'll save you some time if you tell me what to look in to.

Thanks.
