Visual Effect Graph Noise

I'm studying about Visaul Effect Graph. I have some questions about Noise. 1.What is difference between Perlin Noise, Cellular Noise, Value Noise?

2.Why isn't this Perlin Noise executed for every frame? I know Update context is executed for every frame. But Perlin Noise is executed only one time when the particles are spawned. Do I know something wrong?.. alt text

3.What does it mean?

Why add position and total time? What does the result value mean? Also, why is the result value used for coordinate? The noise is connected with Set scale in Update context. I can't understand... alt text

I'm sorry if I used wrong English. My native language isn't English. Thank you :)
