first i have to say sorry for my really bad english, as you see i'm not a´native speaker and i never learnd it well.

I read a lot about gnutella and the new technique and i read the informations provided on this page, but there is still a few questions that i have:

when i'm going online i connect to the server of my internet provider and my computer get's an ip-adress for the time i'm online (i hope this is correct).

Now i start the gnutella programme/protocoll (what is the difference?) and this programme works like a server and it searches for other users, who are running gnutella?

Does it work like an search engine? How does it find other users?

Now i enter a question and this question runs through the gnutella network or my horizon as it is called, but how far is my horizon, what determines my horizon?

Thanks very much for your answers.
