Wireless Q please

[golfmore]

If my wireless network is not secure, how does someone get into my computer?
I have a friend who has a wireless network and a laptop. He can get into the internet from a neighbors network. How does one get to his machine? Or is it really semi secure? Thansk.

If the network is not secured, then a hacker is one step closer to getting into your machine. Normally, someone on your network can't get into your machine unless they have an account and sharing is enabled. Hackers have their tricks and can probably bypass those limitations. Trying to keep them off you network puts another obstacle in place.
