microsoft security patches

[MJS WARLORD]

I been a geek for many years but never understood the following. How can programs such as word have a security flaw that could let hackers take control of a pc. I ask this because yes my hub is on all the time but technically speaking my pc is not connected to the outside world unless I open something that uses the internet. Am I right or am I misunderstanding something.

If you have an internet connection to your PC, be it wireless or wired, it is always connected to the Internet.
