What is a domain name?

Wikipedia tells us: "An Internet domain name is an identification network related to a group of devices or computers linked to the Internet network", and you'll say, this sounds to me like Chinese. To make you understand it better, I'm going to use a simile that will be illustrative.

Imagine the domain is the house in which you reside as a renter, in fact it is as if it had been yours since it's filled with your clothes, your own adornments, your utensils, your memories... but because you live in it you have to pay a rent to its owner who subsequently takes care of other things like paying the neighborhood charge. Additionally, your house is situated in an address and also to identify it has a few, and at times also a letter.
