ISO is the abreviation of Industrial Standard Organization.

In Photography there were DIN(Germany standard) and ASA (American Standard Association) and now standardized as ISO

ISO refer to the sensibiliy of the film/ccd or cmos sensor in digital cameras..
eg ISO 50 100 200 400 800 1600 etc

The higher the number the more sensitive the film/sensor(ccd,cmos) in capturing light.

In the other word higher ISO allows you to take photos in dimmer situation. eg dinner, party, night scene.

Happy shooting !
