| People you've met | 我认识他，我们一起吃过饭。 | 我知道他。(only means you've heard of him) |
| Reading characters | 这个字我不认识。 | 这个字我不知道。(means you don't know about it) |
了 turns 知道 from a plain fact into 'okay, got it, message received.'

| Stating what you already know | 我知道他姓高。 | 我知道了他姓高。(sounds like you just found out) |
