Internet Protocol (IP) is a fundamental protocol used to enable communication between different devices connected to the Internet. It provides a set of rules that govern the transmission of data between devices, including computers, smartphones, servers, and routers. In simple terms, IP acts as the address system of the internet. It assigns a unique numerical label to each device connected to a network, which is called an IP address. It’s like a ZIP code — it tells everything on the Internet where it needs to send data if it wants to talk to you.
