What is a firewall and why do I need one?
Educational Area: Web + Technology
In the videocast I explain what a Firewall is and how the TCP/IP protocol uses ports for connection to other computers. This is a simple explanation using analogies to help understand why port blocking is important. We look at hardware firewalls and software based firewalls and the examples of where we use them. This is a difficult subject to tackle, so I tried to keep this simple to understand. Thanks for stopping by... (more)(less)
