Re: Setting up second computer to internet.
a nic is a "network interface card"
its just your ethernet thing to put it simply, well you might have a wireless one aswell. it should just be called "local area connection" it needs to be enabled and you should see 2 computers with a red x through them in the taskbar if the cable is not plugged in, then it should either disappear if its plugged in or it will just turn into 2 computers
