Guy's, can you help me as this is way over my head.

I feel stupid not being able to understand what is probably an easy concept.

I'll start with the easiest one Major/Ionian, R,2,3,4,5,6,7.

Using virtual guitar I get C Major as C,D,E,F,G,A,B to me that is whole, whole, half, whole, whole, whole, half. I get this pattern with any note that I start with.

Can some one please tell me what I'm missing as I can't interpret this chart because I have no Idea what Root, 2, 3, 4, 5, 6, 7 means and why it translates to whole, whole, half, whole, whole, whole, half.

Thanks in advance.
