What are the Public and Private IP addresses?

Question

I’ve been diving into the public and private IP addresses, as I could understand public IP addresses are assigned by Internet Service Providers, but I couldn’t understand how and by whom are private IP addresses assigned. I couldn’t understand as well what’s the purpose of private IP addresses.

Any help is appreciated. Thank you for helping me out.

Here’s a very simplified analogy:
Private IP addresses are like apartment numbers. No one can find your apartment with just your apartment number unless they are in the building. The building owner can number the apartments any way they want.

Public IP addresses are like your street address. You get your public IP address assigned by your Internet service provider.
