Marcena, great explanation of what a firewall is, the characteristics of a firewall, and the different types of firewalls. Until I started studying computer IT I knew what a firewall was and what its basic task was, but I didn’t know exactly how they worked and how many different types there were. I found your explanation and example of how firewalls can be classified based on their location interesting. I have used firewalls on my store computers but not to the extent that they are truly designed for. I will be looking at changing the type of firewall I currently use.
