What is the difference between a Windows and Network Firewall?
What is the difference between windows firewall and network firewall?
So what is the difference?
Your windows firewall is similar to the network firewall but is physically on your computer. The windows firewall blocks traffic according to rules but ALSO uses "stateful packet inspection" which means packets coming in must MATCH known traffic that has gone out. So it does rules but it knows what traffic should be coming in. This is much more secure as few Network firewalls (on home routers) conduct stateful inspection and are usually just rule based.
Firewalls DO NOT protect against malware.
Firewalls DO NOT prevent you from installing something bad.
Firewalls DO NOT protect you from downloading bad software.
Firewalls DO NOT protect you from giving away your information.
Firewalls ONLY protect you from unauthorized network based attacks against your system.
--So do I really need them?
SH!T THE F*CK H3LL YES!
This is a live map of attacks going on globally. Just follow that link and watch for 30 seconds.

These are two different vendors. Most have their own maps based on their own sensors across the world.
There are thousands of automated attacks every second of every day.
Keep your firewall on.
Even if you have nothing to protect on your network, do you want some hacker using your computer to attack your countries government?
Well, let's understand the basics of your connection to the internet.
This is what communication looks like going out of your computer.
Your Computer ------Router------Modem----Provider--Internet
(Sometimes the modem and router are the same unit).
Your network firewall (in a home scenario) sits on your Router or between your mode and router if you have a separate firewall.
The purpose of the network firewall is to block anyone from randomly coming from the internet and connecting to your home network. (Anything on your network including your network router). The goal is to keep the bad guys out. It does this by blocking traffic according to rules set by default or in advance, or by filtering based on what goes out and if it expects a response. This is your first line of defense from the internet. You want to make your network more secure, set your firewall up correctly or pay someone to setup your firewall correctly. By default you should block all inbound traffic unless you run a webserver out of your house. If you don't know, you don't. Less than .001% of you reading this will run a web server from your home.
