Alright good, and please show some new photos when you try it tomorrow (it will help to see what changes you are getting).
I know what you mean about me speaking "French". I have several photographer friends from college that can get me completely lost talking about more advanced topics. If you don't understand something just say so and I'll try to make it simpler.
Photo noise (also called grain, artifacts, static, etc) are random pixels in photos, that should not be there as they do not exist in real life. It is produced when the camera sensor fails to capture the real color due to limitations or errors in the camera. In other words all those random dots/blocks found in photos.
I took two pictures (just changing my ISO for each) and cropped them to the led light of my camera's battery charger in the pictures to show the noise, and zoomed in 500%. Besides seeing the noise you can also tell that most of the detail is lost due to noise on the right (the hole bevel, led edge, highlight sharpness, etc).
