I just got a new digital camera the other day and finished reading through the manual tonight. In regards to one of the settings on my camera, the manual reads, "When you take pictures in dark places, noise may become visible. To prevent noise from becoming visible, switch [setting] to [setting]."
What the heck does that mean? How does noise become visible!? Will it actually show up when I take a picture? I am so perplexed!!

What, you've never seen noise or heard light? You need to come out of your cave... Just kidding! Noise is the stuff on pictures that looks like colored speckles where there should just be a solid color. It greatly reduces the clarity, contrast, saturation (color), and over-all quality of the photo. If you want to avoid this but continue taking pictures in low light, I recommend using your flash, but if you don't want that (I don't like using the flash as it bleaches out a lot of color; to avoid this, you could take a piece of tissue and hold it over the flash as you take the picture. It will soften the harshness of the flash), shoot at a higher ISO (if you go into the menu on most digital cameras, there is a "change ISO" option. The higher the ISO, the less light is needed to take a picture.

With many consumer type digital cameras, the camera may adjust it's sensitivity or "ISO" setting to compensate for the low light creating the noise or "grain" as xraydelta described it.
Is this a problem? Depends. The amount and look of this grain will vary from camera to camera. "Pixel peepers" will sometimes obsess over this, but in my opinion, it really depends on the use of your image. In a print, it may not be a problem, on a computer display, it could be very noticeable.
If it is a problem your options are:
Don't shoot in low light
Adjust the ISO yourself(keep it low)
Bring your own light(flash, etc)
Don't worry about it and apply "noise reduction" after you have captured the image(noise reduction software is available on the Internet, anywhere from free to very expensive)

They refer to 'digital noise' which has nothing to do with sound noise. A 'noisy' picture will appear very grainy, with different coloured pixels scattered throughout. The problem in simple terms is caused by not enough light striking the sensors and some indivdual pixels incorrectly displaing the wrong colour.
A pixel is a tiny square of colour that makes up an image: if your camera is a 5 megapixel (Mp) one it has around 5 million pixel sensors on the CCD (sensor surface).

Your pictures may not turn out as well. They may be blurry or fuzzy.
