The Noise texture give you the ability to produce a wide variety of noise effects.
how to use
Open the Node editor and prepare the setup as you see in the picture below. In fact, since noise has many uses, we do not specifically say "use it for this or that." But it will be useful in many places and in various scenarios. If you see any "Texture", "Power" or "Amount" channels you can use Noise texture for them (Like float texture).
