What do whiteheads and blackheads look like?

I don't know what these guys look like and the pictures of them online are too ambiguous. Are whiteheads little tiny bumps on your skin that don't burst and may make your skin look rough? And are blackheads the same thing but have a black center?? Do they feel sore or painful to the touch or is that what a pimple is like?? And I guess pimples are the ones where if you do burst them, you see white pus come out and then blood...?What do whiteheads and blackheads look like?
