Question: what is ska and new wave? 

Answer: wow those are 2 completely different musical genres.  Ska, in it's purist form, is from Jamaica in the '60s.  It did gain popularity in the 80's with the two-tone movement, a form of mixing Ska with punk, new wave, rock, and stuff.  New wave was the post punk sound that was a cleaned up version of that music.  They're not directly connected, but they were mixed.
