to understand this question, we must first understand what a firewall does. A firewall is a security system that limits the exposure of a computer or computer network to attack from crackers. This means that all a firewall does is prevent other computers from easily accessing it. If you have a software that is a firewall, then it is looking for hackers trying to get into your computer and terminating those connections. A hardware firewall could be anything, such as a router. A router is a great example of a firewall because it turns all the connections from your public IP address and assigns each computer it is connected to a private ip address, making it hard for hackers to access you computer. Your computer itself may also have something similar in it which would be considered a firewall.
