Nevermind. I know what noise is.
What's ISO?

Its the sensors light sensetivity. If you are in shade, indoors, or anywhere where the lighting is poor, increasing the ISO will brighten the shot without slowing your shutter speed too much or using a flash. Most P&S cameras have this option, but results are usually very poor. The "effect" is like "cracking" open the blinds or curtains during the day to let the extra light brighten things up.
