To add on to this: In South Korean newspapers you'll often find Hanja (the original Chinese characters) on news sites or in the paper or even on the news. It may be simply to clarify a phrase, or for when someone has passed away, there's a character for that. So South Koreans may not know a lot of Chinese characters, but they know the basics and they are quite aware where many words come from-- In North Korea to emphasize their Korean-ness they have little to none of these Hanja anywhere, they don't learn it in school like a South Korean child would, either.
On top of this, you'll find that those English loanwords are almost nonexistant in North Korea. Where South Koreans will simply say "Ice cream", North Korea has the word "얼음보숭이" which literally translates to "ice fluffly thing".
There's also differences in the speech styles (a very complicated and extensive topic in itself) and verb endings. NK prefers some styles where SK prefers others-- But like it was said farther up, the difference really comes down to something like US/British English, obviously different but still very mutually intelligible.
