If your question is in reference to digital images… Consider this:

When you crank up the ISO on your digital camera, you are essentially boosting the sensitivity of the sensor. Much the same as boosting the volume of your home/car stereo when a good tune is played… With that increased volume comes some drawbacks, namely: clipping/distortion. The same applies to digital cameras. Crank up the ISO and you must deal with over-amplification. In your car, this phenomenon is heard as muddied sound. From your camera, it is seen as the noise you are experiencing.

oh that helps, thanks, but does that mean its a lot better to shoot with 200 iso over 400? will it make the picture more clear?

yes..... put simply, the higher the iso the more noise will be produced.

Ideally, you want to shoot at the lowest ISO that you can. The exception being when you actually want the noise.

An example of when you would turn up the ISO when you need a faster shutter speed and your aperture is already open to the max.

^that's what a noisy image is

for reference, that was shot at ISO 6400 on a d100 i believe.
