(Audio Stream Input/Output) is a driver protocol that allows FL Studio to talk directly to your audio interface or sound card. This gives you very low latency (no noticeable delay when pressing a key on your MIDI keyboard).
For example, if you own a Focusrite interface, you would search for "Focusrite Control" or "Focusrite Driver." These drivers are optimized specifically for that hardware and will always perform better than a generic driver.
