Re: The real question...
When you go to connect to your network, your computer first has to send a packet out to see the network. In the process, any other networks close by respond as well, and you end up seeing a list of available networks, secure or not. The software also lists what kind of security is enabled, as this information is sent out along with all of the other information.
That's how you would know that there are other networks around.
