im only 15, but i can help
firewalls are programs that are setup to monitor in coming and outgoing tcp/ip packets (information sent to and from the internet to and from your computer), coming from any program
Each computer that is connected to the internet is connected through 65535 different ports
Each of these ports are used by programs but some are set to be used by only one program, so port 23 is used by "telnet", and other ports by other programs
At any given time thousands of your ports are open, and therefore a potential hacker would be able to dial a connection into your computer.
A firewall conceals all these ports so they cannot be seen. This means that a hacker would not be able to see these ports and enter your computer, an advantage.
The problem with this is that it monitors ALL traffic, which means anything you send can be seen, and logged....
To answer pams question on the "sometimes he can get through", this may be possible if the firewall is set to operate only on certain computers, or at certain times, however it is unlikely this is so, as most companies will go for complete security and monitoring of their employees.
However, it is possible to circumvent a firewall, if anyone wants me to detail these methods plz say
and good luck with the person who is starting on the projecy...hope it goes well
