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.

One can protect their computer hardware devices by installing a firewall in order to prevent any malicious activity to be sent to ones computer. Without a firewall one runs the risk of receiving a virus through email or even by visiting certain websites.
A firewall can be either hardware or software
Implement firewall hardware as well as firewall software on your computer/computer network and implement the use of Access Control Lists (ACLs) on your network's routers.
The Firewall is software or hardware that checks information coming from the internet or a network, and then either blocks it or allows it to pass through to your computer, depending on your firewall settings.

That sounds like a firewall.
