DIFFERENCE between "CART SAVE" and "PERSISTENT CARTS"

DIFFERENCE between "CART SAVE" and "PERSISTENT CARTS"

Hello,
I want to purchase your cart save extension
https://www.webdesigner-profi.de/joomla-webdesign/shop/addons/cart-save.html?lang=en
My questions:
1) What is the actual DIFFERENCE between "CART SAVE" and "PERSISTENT CARTS" ?
2) Does "PERSISTENT CARTS" works for UNREGISTED USERS ?
3) Does "PERSISTENT CARTS" works when computer will turn off and on again?
Best wishes,
Konstantin
