Hi can you talk about VPNs please

[@PowerCertAnimatedVideos]

I will

[@sonakshimakin5748]

Is there a video on VPN and MPLS? Also what are ports?

[@zhar_eng8765]

I using proxy ,,VPN sometimes not secure maybe i think..

[@afsarahmed6081]

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.

Agreed, I learned a lot of this channel.

[@aabid3375]

It is a network based channel

This is explanation for DUMMIES ..... the simplest form possible. Thats why so many understand, because it makes sense

[@sylvestermnyeti1376]

U guys are better than my best Lecturers, u explain concepts in such a way my grandma can easily catch it up. U made me fall in love with Networking again. I really appreciate.

Amazing! Thank you very much for explaining it an way that even slow people like me understood it clearly.

[@gazelle78]

This wonderful video literally spares me the pain of reading through chunky computing texts! This animated style of learning really has to be implemented in all schools of learning

[@philiphy8057]

This is the best explainer channel by far. 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!

Hahaha we all lowkey wanted it to happen. I was stuck on an animation through the whole video so the ending was hella enjoyable xd

[@andersonfiolina2879]

Owning XD

[@roperabay7171]

This channel is one of the best KZbin channels in terms of content. Every single video provides substantial and complete information about the topics under investigation. The animation simplifies the topic farther making it highly comprehensive. Hats-off to the author.

[@klwthe3rd]

I love when the hackers says, "increase attack!" And the skull & crossbones gets through the network firewall but not the host based. The animation us awesome!

[@martincerveny2284]

Unrealistic, but funny - "Hollywood networking" :-)

Seriously I have been attending the classes from weeks but each day I come out with my brain full of doubts......but just today before 10 mins my best friend suggested me to check your channel.... really you are the hero....I got my interest back on networking......Love you sir....thank you Soo Sooo much sir....

[@PowerCertAnimatedVideos]

Thank you.

[@stonebravefoot]

Hey, I just want to say how amazing your videos are in comparison to the networking courses on Coursera. Your use of animation and analogy have made these hard topics so much easier to understand. Keep up the good work!

OMG!! I've been watching hundreds of yt videos, hours spent reading books and searching for explanations on internet, endless phone calls with colleagues until now bc i just couldn't understand the basics....all this until I found your videos!! So many months waisted. You have no idea how stressful and annoying it was and how dumb I felt. I started questioning if going to IT school was a good idea. Sir, i think you just saved my future :)) thank you so much for taking the time and doing these videos. - kind regards, a student who's watching your videos at 3am being emotional and feeling like she had won the lottery in the same time lol

The expensive online colleges are providing us with written materials to learn by ourselves but free youtube videos are by far better. This is one of the greatest examples. I think colleges need to learn from professional KZbinrs.

[@RahulYadav-dx8iw]

I started searching youtube videos when I enrolled in a networking course and I found your videos. Your videos are truly amazing. These videos simplified complicated concepts by obvious explanation and colorful animation with pictures. I have to mention that the videos are better than my lecturers. I intially struggled with networking course, but watching your videos helped me simply comprehend the concepts and pass my exams. Thanks for the videos. Carry on posting more videos.

[@ioanniszafras3745]

Einstein once said : example is not a way -among others- to learn something. Example should be the ONLY way of learning something. And that's what this channel does with great efficiency and effectiveness. Giving small, to the point videos with no extremely technical terminology but keeping this still high end quality in the end ! The world of YT just thanks you gratefully ! I just learned the basic concept behind a rather technical issue !

[@ahmedikr6650]

Take a shot everytime he says firewall

[@guruji3868]

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.

[@philjack8535]

Did a better job in six minutes than a 50 page power point and 30 minute lecture

[@mariateresaluzano4496]

I learned alot from this channel. You simplified a complex topic by making sure that a non-technical person, like me, understand the basic principle behind it and using graphics for a more clearer and visual learning. You got a new sub here. 😊

The value your channel provides in understanding and so so very well demonstrated by your animated videos is just invaluable.

Years ago I worked for a large government agency that dealt with incredible amounts of sensitive information. We created, accessed, and viewed info that impacted potentially millions of people every year. After a 6 month background investigation I was offered the job and yet somehow during my first week of training they never even mentioned firewalls. Given everything we did on a daily basis and the amount of critical data we possessed (seriously), I’m certain they must’ve had one…. But we never heard about it. Thank you for these videos.
