If you mean you want to write a game that lots of people can play in different parts of the world via the internet ('on-line'), then it
is multiplayer that you want.
Multiplayer DB programs aren't just for people to play connected with serial or network cables - it also works over the internet.
However, you have to have a server program running on a machine connected to the internet for them to connect to. Guess what the tutorial was about?

I'm not sure that you know what you actually want then...
With regards to hosting, you would have to have a Windows hosting package to run your game server on - which are expensive (all the cheap ones are Linux based)!
