What is the difference between a firewall that guards for example the CIA, and one that you can buy in the store for $100?

We could tell you, but then we'd have to kill you. :D

Seriously tho' some of the differences between the little firewall boxes and "industrial strength" firewalls is the hnumber of machines it can handle, how much traffic it can support and how complex can the rulesets be.

There is also the availability issue, some of the firewall solutions allow you to put up two (or more) firewalls in parallel and if one fails, another takes over without lose of connectivity.

Hardware or software?
A firewall is merely a set of rules setting waht traffic is allowed in and out, preferably backed up by a more intelligent system, an Intrusion Detection System such as Snort or Tripwire (or Zonealarm under windows, blackice doesn't count, except as a bad joke).

Hardware firewalls are just dedicated hardware.
