Hit Bonus vs Bow Hit Bonus

Is there a difference between +bow hit bonus and +hit bonus? I would think so since there are 2 different types listed on items / weapons.

Does +hit bonus give +bow hit bonus too? Or is there a difference?

Example: Zenith Ring +20 Bow Hit Bonus
lv30 Dex X Armor Pieces +16 Hit Bonus

I don’t a difference when equipping an item with +hit bonus. It leads me to believe its different then +bow hit bonus. Which you would think items like the Dex X armors and all bows should have.
