An IP address is a unique number that identifies a device connected to the internet. IP which stands for "Internet Protocol," is a set of rules that dictates how information is shared on the internet. An IP address is how and where that information should go. If the IP address is like a physical mailing address, IP is the part that tells you how to get there.
Every device actually has two IP addresses: the public/external address which is used to communicate with the wider internet and the private/internal address, which communicates with your local network aka your personal internet router.
Knowing your IP addresses is useful for a few different reasons, such as setting up a file server, adding a printer, or communicating with local devices on the same network. Because your IP address shares your location, it is also a way to understand how your personal information is shared. This is also why more and more people opt to use a VPN or "virtual private network" which obscures your actual location.

Simply Google "what is my IP address" and the result will appear at the top of the page.
