Not a dumb question if you're yearning for knowledge.
Most-all Honda engines are 'open deck'.
Here's a picture of B-series 'open deck' block:
Notice the open trench area surrounding the cylinder walls? That's what makes a Honda motor 'open deck'. Coolant resides in that surrounding trench.
closed deck is seen here (no surrounding trench):

Closed decks are more stable because the top of the cylinders have support, instead of being open. But, you can make a Honda block a somewhat closed deck by purchasing one of these cylinder plates:
This only needed if your making big power with your engine though (turbo).

One more thing about the design. Honda engines were designed with an open deck for a big increase in cooling efficiency. This allows the car to be lighter by using less block material and using a smaller radiator.
