What is a Firewall? (short)

A firewall is a system that is designed to prevent unauthorized access from entering a private network by filtering the information that comes in from the internet. It blocks unwanted traffic and permits wanted traffic.

Thank you so much for creating these videos for free on YouTube!!
I really gained so much knowledge because of your videos, when I was in college listening to your videos I was planning to contribute something to you when I start earning. So here is my small contribution from my side.

I’ve been a data technician for ten years now and pretty much know my stuff, but I still watch these videos because I find them fascinating. And the graphical explanations are so enjoyable to watch.

Keep it up, man! (:

Awesome explanation as always! I was waiting also to see the wall get demolished or catch on fire, like most of the stuff on the animations on your other videos lol
