The internet began as a network before firewalls, where any computer could communicate with any other computer without intermediation; but today there are host firewalls, perimeter firewalls, content filters, NATs, DNS limitations, BGP hijacks and all manner of other mechanisms which limit you and your computer's ability to communicate — and what is a network if not for communication?
