Whats IP means?

(Internet Protocol)

Internet Protocol (IP) is the method or protocol by which data is sent from one computer to another on the internet. Each computer -- known as a host -- on the internet has at least one IP address that uniquely identifies it from all other computers on the internet.

Why is IP used?

In essence, IP addresses are the identifier that allows information to be sent between devices on a network: they contain location information and make devices accessible for communication. The internet needs a way to differentiate between different computers, routers, and websites.
