Windows Firewall

Hey kiddo, do you know what a firewall is?

Well, it's like a big wall between your computer and the internet. It stops bad guys called "malware" from sneaking into your computer and stealing your information or messing with your files.

Nowadays, almost all computers have a Windows operating system which comes with a Windows Firewall. It's like a guardian who keeps an eye on everyone who's trying to connect with your computer from the internet. Its job is to decide which "traffic" to let in and which "traffic" to block.

Sometimes, when you try to use a new app or visit a new website, the firewall may ask for your permission to allow it. It wants to make sure that everything is safe for you to use.

So, in simpler terms, the Windows Firewall is like a guard dog for your computer that protects you from online threats and only lets in the ones that are safe.
