What is the cookie law in Italy?

Excuse me, could you please elaborate on the cookie law in Italy? I'm curious about the regulations that businesses must adhere to when it comes to the use of cookies on their websites and how this affects user privacy. Specifically, what are the requirements for obtaining consent from website visitors and what are the penalties for violating this law? I'm also interested in knowing if there are any notable differences in the cookie law between Italy and other European countries. Thank you for your time and assistance.
