What does Instant return, electronically controlled mean on Nikon cameras?

I'm looking at DSLR cameras, and came across the term "Instant return, electronically controlled" when reading about the Aperture on a Nikon D3200, can anyone tell me what this means?

Instant return, usually applies to the mirror - invented by Gamma (Hungary) and perfected by Pentax, the reflex mirror drops immediately after the exposure is made, opening the viewfinder again.

Electronically controlled usually refers to the shutter - the time it's open is measured electronically.

Applying both to the aperture means (like every other DSLR on the market and not a few film SLRs) that the aperture is set using the body controls and that the iris diaphragm opens up immediately after the shot is taken - it's only marginally less obvious than, 'Takes photos.'

Fully automatic. It's actually standard to all dSLR's and late model film SLR's so whoever put that there's just overzealous in selling that item.

Don't worry about it! It just means that the shooting process is electronically controlled and the mirror returns to its position immediately after the shutter has been pressed.
All (D)SLRs have those features.

When talking about aperture, it is referring to the fat that the lenses for the 3200 are generally "G" lenses, which do not have aperture rings but the aperture is set electronically in the camera and not on the lens itself as on the older Nikon lenses prior to the "G" designation. However, many of the older lenses with aperture setting on the lens did not have internal focus motors and so can't autofocus on the 3200 which does not hav an autofocus motor in its body
