Team Comp questions

Can anyone link to a post that describes dive comps vs split comps etc?

I'm Looking to educate myself on support picks based on that sort of idea. I realize I'm am elo, but I think it's probably a good habit to get into.

If you have any thoughts tip's I'd love to read them. Especially from a support perspective. I welcome all input from Iron to GM.

P.S.

By the way I am Googling it.
