"The card itself, as I stated above, is an actual mini-computer.
But it's also more than that. It has it's own miniature hard drive,
CPU and DDR memory chips. While it's unlikely that you'll be
playing Quake or anything hardware intensive on it anytime soon,
what it is capable of is more than sufficient for the microscopic
hardware it has.
"And what task is that? Well, being a hardware firewall for one.
But at the same time it's not your typical hardware firewall. Most
hardware based firewalls tend to be the more traditional kind,
which operate directly on your network outside of your PC. The
problem with that is, you need a physical hardwired connection to
make use of them. If you're using Wireless, you're kinda up a
creek, or forced to use a software solution. If you're on Windows,
you also have to include an antivirus with that firewall, and much
more."
