Firewall system in computer help you secure your computer manage incoming and outgoing connection, typically identified using port, either you want to allow some specific port or block it. It useful for preventing unauthorized people using our computer resources, stealing our sensitive data and any kind of hacking activities.

Windows 10 by default have firewall, so it is safe for you, you don't need to worry about hacker or bad people doing bad things to your computer while you are using public internet. Mac and Ubuntu or any other Linux don't enabled the firewall system by default, if you want to enable them, we will covered it later in this blog.

It is not necessary for you to have a firewall activated if your computer is not visible by public, either by public internet, like if you are using WiFi cafe, etc. Even though you are using public internet and no firewall, it is not that always something bad will happens to your computer. Our computer is getting smart and less bug day by day.
