What "NDA" stands for?

[MPDota]

I just read this ( http://wccftech.com/nvidia-geforce-gtx-1070-custom-models/ ) article and it says "NVIDIA will officially lift NDA". Can anyone tell me what it means, i searched google and found stuff about food?

non disclosure agreement

long story short, you dont say anything or give info about the product when under the agreement.

I agree with gokitty. It stands for non disclosure agreement. That means that even if you were given a review model (or a retail model) that you are not allowed to say anything about how it performs or how you feel about until they lift it.
