What is downsampling?

I am very confused about downsampling.

D800 files compared to D3s, D4, D700

e.g. in this review


Does it mean "binning"?

That is, combining data from 4 pixels, and use it like a large pixel (4 times the area).

On the camera, we can also select the number of Mega pixel we want?
I don't think we gain "binning"/ advantage in High ISO performance.
