terminology

This might seem like a silly question but I want to get my terminology correct. Please do not delete. I will be more than happy to delete the question myself once I (with the help of a few people I hope) get to a consensus:

This was my understanding:

DNS root zone = .
DNS root domain = (nameless)

However, after reading the Wikipedia article, I'm not so sure:

A domain name consists of one or more parts, technically called labels, that are conventionally concatenated, and delimited by dots, such as example.com.

So this would lead me to believe:

DNS root zone = .
DNS root domain = .
DNS root label = (nameless)

Does this make sense? What is your understanding?
