Why does my ISO 100 make noise?

That means a photo taken with a lower ISO and underexposed will have MORE grain than an image taken with a higher ISO, but correctly (or even over) exposed..
Does higher ISO mean more noise?
If you are shooting low light then a higher ISO will amplify the signal but also amplify the noise. So in most cases of less than perfect light, a higher ISO will have more noise than a low ISO. Some newer camera systems are considered to be ISO invariant which means that the ISO wont introduce it’s own noise.
