I heard about Firewall for the first time 8 years back during my first year of engineering. Have seen videos on Firewall from the OEM channels like Palo Alto, Fortinet, etc but I must say this is probably the bestest best explanation I have ever seen 👍.

Sir, the way you teach, nobody else does. Thankful to all your videos.

[mayamaya]

Just like what you have done in many of your videos in which you provided simple and relevant analogies for each concept; this has made IT relateble for a non-IT background like me. Unlike lots of IT videos out there, yours are clear, concise and relateble. Keep up the great work.
