is a DNS Server kind of like a translator? the domain name is the input and it finds the corresponding IP address?

is a DNS Server kind of like a translator? the domain name is the input (treehouse) and it finds the corresponding IP address for that web pages host server? DNS Server then packages that together with the return to address (for the device that requested it)

Not a bad analogy.

Yes, it does essentially translate a name into an IP address. But it's a bit more than a pure translation because it relies on collected data that can change. So the "translation" you get today might be different than the one you get next week.

Yes.

I wasn't really understanding this so I went to look it up and I recommend it: https://www.youtube.com/watch?v=72snZctFFtA

it looks like math formula like (a+b) a=8. b=9,c=?, so what we type as words r converted into numbers

Rather than a "translator" or "formula", you might think of it as a "dictionary". And this dictionary is constantly being changed, so you still need to look up anything each time you use it.
