Does Adblock actually stop ads/images being downloaded?

Hi, sorry if this is a naive question from a new user of Adblock.

Does Adblock stop an ad or image from being downloaded, or does it download and merely prevent the item from being displayed?

The blocking filters avoid downloading the elements.
The others - hiding filters - are hiding the targeted elements (because they are not external objects but only elements builtin the page)
