DNS & TCP/IP

HI there, loved the course - one thing I'm confused about- when you type a url in a browser is the first thing to happen that the url resolves to an ip address vis DNS & then this Ip address is included in the internet protocol layer & only then can the packets of info be transmitted across the routers?

I thought the DNS 'forwarded' the request, thus being....

Client -> DNS -> Server -> Client. ????

According to the teachings of one STUNNING! Joy, the process goes like:

CLIENT--> DNS--> SERVER (INPUT ROUTE) and then, from..... SERVER--> CLIENT (OUTPUT ROUTE) --B/C the IP address does not require translation back through the DNS to get back to the CLIENT (YOU!)
