What is the difference between a CNA and a LNA?

Hi, I live in PA and originally I was planning on going to school to be a MA, but after hearing there are little to zero jobs available in that field I am considering a change to be a CNA. Then I started seeing all these comments on here about becoming a LNA. What is the difference between the two or are they the same thing just different area's label them differently. I've never saw a listing in the paper for a LNA..its always CNA. I would like to go to school get certified or licensed if LNA is a bit higher up w/ roughly the same schooling and once my son is old enough to start Pre-K i'd like to then start taking cles to work my way up to be a LPN then RN eventually. But right now I'd just like to know if there is a difference between a CNA and a LNA and if so what it is. Thank you so much.
