What is the protocoll of the Internet?

If you are referring to IP address, this is a special identification number that is assigned to all machines connected to the internet or intranet. It is comprised of 4 sets of number ie. (64.54.123.26) Where each number can be anything from 0-255. This number is unique to each system and acts like a physical address for your computer. When you send a request for data this address is attached so the machine you send it to can know where to send its response. No two computers have this number.
