  • This is an animated video explaining what a network firewall is. 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. A firewall blocks
    unwanted traffic and permits wanted traffic.

      Is a firewall a different networking device or just a virtually installed with OS? This doubt is because you said some computers have pre installed firewalls.

Unfortunately most smart tech people are pretty bad at explaining to others, which makes it super frustrating and at the worse of times makes me feel stupid. However, when I see these videos explained so clearly, it changes my whole look outlook on my abilities and the IT field. I can't emphasize how much these videos mean to me. Thank you!

    My understanding after watching this video is very vivid. The simple way I understood and will teach others in the future is that our network is like our house. Network based firewall is the main gate and host-based firewall is the door of room. Former protects the whole house and later protects the specific room. Both are needed to be safe from intruders.
