What is a Firewall?
Вставка

- 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.

Hi can you talk about VPNs please
I will
Is there a video on VPN and MPLS? Also what are ports?
I using proxy ,,VPN sometimes not secure maybe i think..
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.
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.
Yea im in networking right now test out us ok but this is better
me toooooo :(
Very nice
Amazing! Thank you very much for explaining it an way that even slow people like me understood it clearly.
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
Best IT channel on youtube...
Agreed, I learned a lot of this channel.
It is a network based channel
*Linus:* 10 - 20 minute video and sometimes goes off topic
*This guy:* jumps right in with no sponsorships and no rambling, easy for beginners to understand
@@aabid3375 it also covers a lot of other IT topics
This is explanation for DUMMIES ..... the simplest form possible. Thats why so many understand, because it makes sense
Seriously!😢
I don't know how to thank you 😢❤, I nearly give up in IT because I wasn't getting an image of what ever I read and being taught by my lectures, I came across your video around 1am in Ghana, it 2: 50 now, and the impactation is like I joined the channel long time ago ❤😭. God bless you and your team
You're welcome 😊
The ending is just perfect. A burning router that is literally on fire. Well played.
:)
Spoiler alert!
idk, it actually made me kinda sad for some reason :(
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
Owning XD
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!
P l l p p p p😊 p
Very true
Did a better job in six minutes than a 50 page power point and 30 minute lecture
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!
Unrealistic, but funny - "Hollywood networking" :-)
is it huh
This channel is one of the best UA-cam 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.
I passed my 902 part of the A+ Cert CE and am now A+ Certified. Thanks a lot for your animated videos!!!:D
Congrats dude!!
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.
its surprising how many people in IT like me have got around so long without learning these basic concepts until today.. thank you very much!
There's hundreds of comments under this material, but I also need appreciate your involvment to create such good guide. If there were more materials like this, people can learn smart things to do their jobs in 6 month in comparison to study 3 or 5 years where teachers teach so boring that nobody listen. Very good !! :) Internet needs such people like you.
That attack at the end was personal 😂
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!
Bro?
Love your animated teaching videos ... clear, concise ... easy to comprehend. New subscriber ... Keep up the good work.
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.
Hello MR, I just wanted to tell you that you are an excellent teacher and also very clear in every single video. Thank you.
The videos are so well defined and explained in detail that even a fresher can understand all the concepts.
this is the first video i watched on youtube. after that no need to watch another videos, very easy and clear explained. i understood the uses of firewall. God bless you and keep it up.
Lecture with clarity... Thumbs up for the excellent delivery from us at Rehoboth Professional Services in Nigeria
Best IT channel ever! i love the visualization of concepts and how well you present and explain them. thank you! SUBSCRIBED
Thanks and welcome
The most concise explanation i've ever came across on the internet. 100x better than at school
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 !
I'm so glad I found these videos. I started working in IT a year ago and came across situations I don't fully understand. These videos are truly great at helping gain more technical knowledge in my field. Thank you so much.
You guys make IT learning so easy. your animations suffices and sets a good narrative
Your teachings are much more easier and can be understood very fast. Thank u so much
I love your animated tutorials which helps to understand the concept very easily. Thanks for all your hard work!
Glad you like them!
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....
Thank you.
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
I totally understand how you feel! I’m still learning the basics and I graduated with a cyber security degree two years ago. Currently studying
for security plus
👍
You are incredible. These videos are so useful. Thank you for taking the time to make and upload these.
I like the way you explain, its simple and you cover all the important topics also its organized.
Thank you.
Best IT channel on youtube , explanation is in very simple and effective way, love this channel😊
Number 1 IT Channel!!! The visuals that you provide are super duper helpful
Thank you :)
Thanks so much for this video! I'm in a college IS class right now and this channel is helping me a lot with some basic concepts! Keep it up!
Legitimately the best networking channel in UA-cam.
Explained so nicely! This is the best channel by far on UA-cam for explanations of tech-related topics
I subscribed to your channel just by watching this video. Very great explanation. We appreciate your effort a lot. This is by far the best video I have ever seen about firewall. Keep up with your good work and keep producing some more Cybersecurity videos so that it can help those who are majoring in cyber security as we know Cybersecurity has been one of the most important and demanding subject of today’s world.
The ending was DRAMATIC!
Sir you have my respect and 100% attention. You just summarised alot if information in a 6 min video..AMAZING job !!!
Thank you very much
Glad you enjoyed it!
I love your videos. They explain things so that I can really understand computing. Keep 'em coming!
Glad you like them!
I love your classes...I won't miss even a single video...coz it helps me a lot...n I can understand clearly..so thank u so much
I am working on getting some certificates for college, but I am admittedly not that smart. Your videos are helping me connect the dots better than the videos I have to watch in my classes. Thank you so much!
I have watched all your videos, many twice or three times. I learn best with animation or graphics and am thankful for the time and effort you put into them!
This video explained very simply what my lecturer tried to explain in 2hrs!!! Thank you
I'm so touched by the firewall lecture
I love this channel and the animations bring it to life. Thank You for keeping things simple
One of the best explanation ever seen.
Lol the ending though xD
Thanks for the video, that was really helpful!
i have learnt from PowerCert more than my own teachers, thank you
Crystal clear explanation and best ever anaimated videos you have on your chanel. I have watched almost all of your videos. Thank you. Keep up the good job.
Great Video animation...No wastage of time..Short and crisp explanation!
Studying for my A+ cert. Appreciate your work on all these videos!
Thank you
Your channel is a treasure
period
this guy been saving my life for years now, and this visualisation is just top notchh
The value your channel provides in understanding and so so very well demonstrated by your animated videos is just invaluable. This video was hilarious 😂 🤣 too at the very end, but it effectively conveys the message of the topic. But each topic is so simply explained where I can say I get it and much easily done and done better than explained from so many other sources at its basic level. Keep up the very good work.
🤣
i always come back to your videos when i have to revise any concept :D
Thank you for sharing and for making the complex simple.
Well done video! You can turn something from complicated to simplistic. Thank you for your tutorials!
You explain complicated issues in simple way, thx really, it is great help
Thank you for the amazing video, I have a project due soon about Firewalls and your video summarizes it easily and perfectly.👏
The content on your channel is addictive. Great job. Congratulations!
Glad you enjoy it!
You literally explained what firewall means more better and clearer to me than my IT teacher
number 1 networking channel. you produced best animations please have more videos on all networking topics
this is a very useful channel for learning IT concepts and the animations make it clear and interesting. This video is very well-made, the ending was so cool. There are lot of visual learners like me. Instead of some boring old man reading slides :)))) my favourite tech channel!
Thank you.
U changed my understanding, thank you!
This is by far one of the best channels to explain networking!
Thank you
Very well done sir! I was completely in tune with your explanation and now have a full explanation of a firewall! I just hit that subscribe button!
Thank you so much for your videos. I was struggling with my IT technician course until i came across your UA-cam channel.
Your videos are easy to understand and are straight forward.
I was going to buy a book which is really expensive, but thanks to you people I don't have to.
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. 😊
Glad it was helpful!
❤
Perfect timing... I am just about to get started with my Networking job...
😁😁😁
how did you get a networking job and know nothing about firewalls
@@carsonshreeve4691 I did not say that I did not know about Firewalls. I said the timing was perfect to learn more about it.
💯💯💯💯
@@carsonshreeve4691
It's never to late to relearn and refresh one's memory. Yes I've seen x(enter job field) done a thousand times but I love watching new employees because it reminds me of where I started and keeps me on point that I'm not slacking or *maybe* they learned something new that and old guy like me can pick up.
Perfect timing
Last night I was just looking for the firewall but couldn't find and saw the video on DMZ...
Thanks a lot
Thank you saved me a lot of time trying to browse videos for an actual working one
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 UA-camrs.
Animations are like a computer horror story.. Excellent explanation and animation.
I was not interested in networking but after watching these videos it has became one of my favourite subject. Could you please includes topics like DNC,iDRAC.. as well.
An exceptionally professional way of explaining 💛💛💛
animation and explanation is very good
PowerCert Animated Videos after seeing that he's doing a video on firewalls: "I've been waiting for this moment for all of my life."
Excellent this type of education must be provided widely to explain the students easily.
Thanks for making this wonderful animated video. You explained it simply. 👌👌👌👌
Joining for the first time. Your channel is very helpful.
Best PC educational clips on youtube by far!
thanks from India, every topic when search in youtube your wonderful video come first and from that my all doubt get clear. again thanks, As I am preparing for ccna exam, and your video help me lot.
Oh my God.. Thank you for all your helpful videos. I'm binging on them tonight....
Thank you so much for this explanation and visualisation
m so happy to end up with your channel, so damn good information and explained so nicely and in simple manner. Great job done!
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. I’ve learned so much.
what did you do or what was your role? Just curious
the animations are beautiful! thank you so much for the effort!
Thank you for your hard work that you put in visual components to explain to us....
Superb way to explain technical concepts. Thanks a lot for your efforts
Oh God!, what happens to the router at the end! 🤣🤣 too hilarious......Also thanks for such a wonderful explanation! :)
Glad you liked it!
Best IT channel on you tube. Thank you
Excellent simple full of clear information
Can i say you r the best teacher. I seriously love the way u teach. Thank u so much for making my life easy 😢😘😘😘😘

5:47 was the best part of the animation, all those little skull and crossbones getting through
Great animation and explanation of what a firewall is.
Really great animation and discussion. Thank you!
These videos are golden, thank you!
Thanks, Sir. Learned a lot from your multiple videos
