What's the difference between “default gateway” and “preferred DNS server”?

My hosting provider gives me an IP and an IP gateway address. I configured my domain to use the IP. I don't understand what is the use case for the gateway.

The gateway is the "next hop" - basically, your PC connects to the gateway IP to get out onto the rest of the internet.

    As a note, it does not actually have to connect to the internet, it could be any network (even one that is totally internal). – soandos Dec 21 '11 at 23:14
