i've been purchasing some textures of Textures.com. The thing is that some of these have a displacement and some others have something called "Height". At first i thought it was the same thing but after watching closely, they don't seem to be the same (or maybe i'm bad at observation).

The thing is that i need to know what does this map mean. It's the same as a "displacement" map?

If not, where should i connect it in the node editor?
