What is a software-based Firewall and why you should install a Firewall? 

This is just like any other program that you would install on your PC, except it will provide you with network security features. These firewalls are not much different from hardware-based firewalls, the only difference between a hardware and software firewall, is that if you have a firewall program installed on your PC it will only provide security to your computer, not your local network. The other downside is that it will only scan network traffic coming to your PC. It will not have scanned anything coming from the router, switch or any access point you might have.
