It is a software program running on your computer that allows the data to pass through it, if you have programmed the software to allow it. You simply select which of your applications, like web browsers,  client, mIRC, etc. you want the firewall to allow to access the Internet. These firewalls are mainly designed to protect the single computer that is running the software. Ideally, you will use both a hardware and a software firewall. What next?
