Pipe lock is evidentally a button on some routers that when pressed with severe all connection to the internet via cable or dsl. Apparently my router does not have this feature whereas my son's router does. But let's go further with the idea of a firewall and being hacked.
I'm wondering exactly "how" a firewall works. Does it physically prevent anything from outside entering one's computer OR does it simply render the computer invisible? If it sort of gives my computer a (Star Trek-like) cloak of invisibility, would it be possible for someone (although highly improbable) to penetrate to my computer? Currently my little network (two computers) sits behind a Linksys router as indicated before and both computers have software firewalls. So... is it a physical impossibility to penetrate to my computer or are we simply hidden from the internet community and our being hacked is remote at best?
If it "is" possible to penetrate through to my computer network, what is the best advice in terms of being "away" from the computer for several hours? Do you actually turn if "off" or just log off and let it be? And come to think of it, since just logging off really does nothing, since you're still connected (cable connection here) what would be the point of even doing that?
Thanks for any insight here.
