I know it has to do with protecting a computer but what does it protect exactly?
A firewall is a piece of software or hardware that helps screen out hackers, viruses, and worms that try to reach your computer over the Internet. If you are a home user or small-business user, using a firewall is the most effective and important first step you can take to help protect your computer.
It is important to turn on your firewall and antivirus software before you connect to the Internet.
