6 hours, two chapters read and time lost. 14:57 of watching a video and now I comprehend what I was supposed get out of two chapters. I should of gave you my tuition and hired you to tutor me for a Master's.
Thank you Riggins I consider your lovely message as my fee. Thanks for taking out time to write this feedback, its comments like these which keeps me going. Thanks Anshul
My pleasure I messaged my classmates your video we have an assignment due and all this & proxy and reversed proxy are combined. I just watched that too. Pls let me know your email address. I can send my assignments to you to give some ideas for content. My mom watched your video too 60ys+ & she understood it too. Your educating generations, that is huge.
🙏🙏 Oh woow thanks to your Mother this is my inspiration to teach I. T. across ages, industries, countries my id is anshultiwari353@gmail.com
You are a PERFECT Teacher as you have explained the basic concepts in the best possible way. I completely agree with Riggins that this video is worth many hours of reading the complex content available in books. Many thanks to you Anshul.
I have subscribed your channel but able to see only 12 videos. Is this fine or there is more content? I would love to study networking concepts from you because there cannot be a better teacher than you. I have always had confusion understanding them. Pls upload more of these lectures for us. Thanks.
After years of working in the IT industry (I'm an IT Manager and Systems Administrator), and having also studied engeneering, I don't think I've ever seen someone explain something in such a simple and effective way. If you're not a university tech teacher, then you should be. This is gonna be a great video that I will forward to my little 12 year old brother who wants to follow the same career as me (I'm not a very good teacher so I have to find alternatives for him). Very well done and I hope you keep doing this for future generations. Thank you.
Thanks Humberto your comment made my day ❤️🙏
@@ITkFunde
Hey, would you mind if I consulted you about your profession?? Am looking forward to the same career thou first need some guidance,,thanks.
🙏🙏🙏
For someone recently graduated with a CS degree. What type of job would you apply for?
I am 56 and decided to go back to school to learn to code! You have changed my life. You have made the concept simple to understand. Bless you!!
Awesome 🤩 How it’s going on now ?
❤,,, GOD BLESS YOU ,,❤
47 here... Never too old to learn. 🎉
OMG, I have spent hours trying to get a firm grasp of these basics, I've talked to many, many IT folks, and still struggled. Your paradigm of the school is so simple and direct, and finally everything clicked. Thank you!
Thanks Carlos ☺️
i have been in IT for 30 years.... no one has ever explained this so well...... Nice job sir.
from your experience what should an IT technician masters in this field? what should I do to provide value to the companies?
@@ariffaiman5985 I work for a very large fortune 50 IT company, and most senior executives that are responsible and accountable for the availability of their services to their clients, end up at some time in their month of every year in the middle of some type of a major network outage and if you could have these sea level executives have a better understanding of cloud net work private Netwerk hybrid cloud net work etc. etc. I think you could have an excellent package that you could sell that they would want you to either present to them virtually question and answer or in person.
@@vrt1032 what a great insight! thankyou for your time sir 😊 so its so demanding even in a very large companies. Do you think other languages is important in order to work with our clients? Is it mandarin or? How do we upgrade and improve our career if you dont mind to share sir..
@@ariffaiman5985 I believe so. These c level executives want to be schooled in network technology jargon and architecture to make them sharp in a world where everything is cloud. Good luck
@@vrt1032 thanks a lot sir ☺
I'm 43 and I've just decided to go into IT field. I'm taking my very first course soon and I can't wait to get started. These videos help someone like me understand these concepts and it won't all hit me like a ton of bricks. Thank you!
Thanks a lot and I wish you all the best ♥️♥️🙏🙏
Best of luck 👍
Hi!how is it going for you so far
hi,i am thinking to take on the same step, how did it work for you until now?
I’m 2 year younger but we’re on same page to get into the IT but I don’t know how or where to start .
So where did you start and I wanna see if I can follow your steps thanks boss
I'm working towards my cybersecurity bachelor's degree and this video finally got me to understand subnets. Thank you, you're an excellent teacher!
You’re the only person I’ve found that can explain things this clearly. I’m not like uhh what.. let me rewind.. it just makes sense. Thank you!
Teaching is an art, and you know that very well. We have many people with good knowledge but very few teachers like you who can explain complex concepts in simplified terms.
no doubt
ua-cam.com/video/q1Qjn6QV7tU/v-deo.html
Well said 👏
He's the only teacher u can understand even when is speaking a different language
thanks Sunil ❤️
I work in the telecom/networking field and wish I would have found this video when I first started. You have a gift for teaching and simplying complex concepts!
Thanks Michael
3 minutes into the video, and I know I'm going to comprehend it way better than I have any other videos. for non-technical people like me, this is a gem.
ua-cam.com/video/q1Qjn6QV7tU/v-deo.html
I’ve never thought these concepts could be sooo easily explained by someone.
I am leading the Risk & Compliance of my company, and I closely work with Network Security team. These concepts help me a lot to understand their lingo! Thanks!
Thanks Ashay for such a lovely feedback means a lot please keep supporting 😊
Mayang cs jangan ikut2sn konten bawa gala. Seperti fuji kalau fuji kan memang dari bayi sudah dekat dengan gala jadi sudah bagus sudah menyati , jadi srmua yang lihat enak melihatnya, tapi kalau mayang apa? ???cari anak yang bukan gala ysh supaya .............
Watching this in 2025 and it was SO helpful. Very well explained. You have a gift for teaching
THIS IS WHAT A LEACTURE IS EXACTELY CALLED
THANKS A LOT SIR.
Thanks Nihal 🙏☺️
I know right. I dont have to study, i basically remember everythig he lectured in this video
I wouldn't say lecture I would call it teaching.. IT K Funde is good teacher
Honestly, even though I'm within tech support, I never knew the networking basics. This short tutorial has helped me understand it much more and thank you for that.
Thanks Vanja ☺️☺️
me too bro
I never ever comment on UA-cam videos, but this guy just made the most basic and comprehensive intro to networking I have ever seen in my entire life. Did not even have to google anything from what he said because it was very clear.
I have more than 12 years experience in application development and system administration. Still I find many of these terms confusing. Thank you so much for explaining this in very simple terms. My respect.
Thanks Vishnu🙏☺️
Same, lol, minus networking experience. This was awesome.
You're a sysadmin and you forgot about firewalls and switches? 😮
That's like 80% of the job lol
Today I literally understood how basically networking works. If every IT student gets a teacher like you, they will never go to banking or marketing fields. This 14 minutes video is way better than 14 chapters of long networking book.
Thanks Shah for your generous feedback it helps me stay motivated 🙏☺️
Hey! Today was my first day back in school, and I’m planning on majoring in network management. It’s always interested me! I spent 8 hours today reading in a textbook, completing assignments and watching lecture videos. I was then asked to describe a network, and was surprised that I felt lost. This video really turned things for me around, and now I understand the basics. Thank you so much!!
These are the guys who used to help their friends to clear exams by explaining concepts to them, just minutes before entering exams halls. 😁
no such thign as frienx or familx etc
👍
Yeah I would love to have a friend likehim✌✌✌✌
Indeed
True 😁
Wonderful explanation... can't thank you enough for this video. Regret exploring these videos so late but better late than never. You are an amazing teacher. Well done. I am a woman on career break and trying to resume career in my previous IT domain and there could have been no better way to start refreshing concepts except for your videos. Simplicity at its best. God bless you. ✌👍👏
Thanks Chitra for your support, such feedback helps to keep me going🙏☺️
I wish I had you as my Math Teacher when I was at school! You reflect what all teachers should be! Subscribed.
Your way of making people understand and explaining it with school example is just too good , like anyone out there can understand how it works watching your videos. SIMPLY GREAT WORK !!!!
Thanks Anjali :)
This helped me a lot. I was struggling to understand the Network Technologies lecture today. Thanks a million.
Thanks Andre glad to know it helped !!!
Man you are so eloquent and on point. You have compressed the staff into small manageable bits that are so easy to understand. Great work. I have learnt a lot today, in just 14 minutes.
Thanks Leanmore appreciate your feedback it means a lot to me 🙏
Finding this channel is one of the best things to happen for my IT learning experience, you visually explain things in a way that technical books can't, and the concepts are easy enough to digest that I can translate these lessons into more detailed or technical terms. Thank you so much!
Thanks a lot 🙏
Honestly using the school environment analogy makes this so much easier to comprehend. You are a genius, Bro. Now I can explain this concept to a 6-year-old and he will understand it. Thank you so much Bro
Thanks Chris ☺️☺️♥️
Thank you so much for the lovely explanation. They say that, " if you can explain the subject you've learnt to even 5th standard child and he understands it properly, then you're in control of that subject" and this clearly shows it. God bless you brother ❤. Please keep going and help more . Thank you😊.
Thanks Bhai for your kind words I am just a learner like you and trying tonshare whatever liytle I can. Please keep supporting 🙏❤
Man... I never saw anyone explain so simply yet so clearly....you have my deep respect..and I'm grateful for the AMAZING content
Been doing networks for a long time and this right here is one of the best explanations I've come across on UA-cam. I was curious what you had to say and this is good even for the most seasoned engineers. Keep up the good job.
Thanks mate coming from a Pro like YOu means a lot ❤️
Hey friend, just want to let you know that you are easy to understand. I normally get annoyed when things don't make any sense but you have the "IT" factor. I mean you are very detailed and not boring at all. Hope you keep making more content like this.
Quite easy to understand! I just wonder why it seems so complicated when you hear some other people explain the same concept. Thank you so much. I do believe that teaching is a natural skill. You are indeed a teacher!
Thank you for your kind words means a lot to me 🙏
Yes indeed. ! As a former teacher, I can relate. Teaching is an art! Most people on UA-cam teach in an abstract way. You see how wonderfully he uses the classroom with children to explain these network concepts in a very simple and easy to understand way.
Thanks coming from a teacher means a lot❤️
Thanks!
Thanks Pete for your kind support ❤️
I’m so glad I scrolled down a little to find this. Thank you! Your school analogy for the lan, router, wan, and subnet, in particular, were presented so clearly and that helped a lot. This video deserved far more views then it has and is for sure the best on the topic here on UA-cam. No question. Thanks again.
Thank you Jim 🙏🙏☺️☺️
I love you man. Same here… in 15 minutes listen to him in english i have learned more than 3 hours listening brazilians teaching (my native language) 😢😅🎉 thank you
Thanks Edurado ❤️❤️
I am a recruiter and I am constantly hiring NW and NW Sec engineers... your video with real examples summarizes exactly what I am after.. keep up the great work..i absolutely love this..!!
Thanks a lot
Sir if I were there in person, I would have thankfully given you a handshake. Thanks to this video I was able to secure my entry level sysadmin job, as your video simply helped me map out the various knowledge about networking in a practical and easy to digest way. I wish you more success.
Thanks dear so happy for ypu god bless ♥️♥️🙏🙏 pls keep supporting
Thanks! Great examples
This breakdown is worth far more than $10!
Thankyou Maya for your support 🙏❤️🙏
Thanks a million, I was hopelessly looking for someone to explain these basics to me as if I was five 😂, and it worked!
Thanks Reem for your feedback, I try to make it as easy as possible as that is the way I also understand things better. Keep supporting.
This helped me out a lot. Appreciate the layman's terms instead of over complicating things or using long complex definitions.
Thanks Alux🙏☺️
So helpful
Wow. this fella broke this stuff down to where a 5 year old could understand. Truly, amazing. Good work
Thanks bro ♥️♥️
Just wanted to comment about you saying thank you for 500 subscribers back in May 2020. You've now (on 30th August 2023) have 365k subscribers. Good job!
Thanks I am grateful 🙏♥️ thanks for ur kind words
and of today 02/04/2024 theyre over 410K Subscribers great job
im honestly overwhelmed by how humble and yet so good this teacher is. This was just so good, too good. may GOD Bless you.
Thank you Kimberly for ypur kind wors means a lot ☺️🙏
YES SURELY
Cant thank you enough, seen many videos and read books but didn't get the clarity until I watch this video on network basics which is just 14 mins video. Great explanation. Will watch other videos of yours.
Glad it helped!
thank you for this video! I have my cybersecurity certificate exam on Monday but I was still struggling with the chapter about networking because my course just presents this information through very dense paragraphs which my ADHD brain hates lol I always learn concepts better when someone says it all out loud along with visual examples so I'm so grateful that this kind of learning is easily accessible and free nowadays
I am into vfx and animation , but always wish to learn networking . the way you explain the basics is outstanding . today i got to know the exact meaning of all the terms after watching your video . earlier i was like subnet , it should be this and have to put this without knowing the reason , your video cleared all my 10 years queries. Lots of love. Thanks infinite
Thanks Sayed your comment made my day 🙏☺️
I’ve literally just had a whole day of learning networking and this guys just explained it all to me in less then 20 minutes
i love your analogy , makes it easy to understand every concept without cramming nor forgetting easily..
Thanks Mate !!
Mmmm
You're a brilliant teacher. Indian people are masters in IT. Congratulations! I'm studying for Azure certification and this helped me immensely!
Thumbs up to this man. Perfectly explained and helpful! I watched it 3-4 times and now I know how my Lan works and communicates.
Thanks ☺️☺️♥️👍
Thanks so much for simplifying the concept of subnetting! This can get lost in translation when people are focused on calculating subnets. It's so important to get back to the basics and explain why we do what we do. Great videos, subscribed - keep it up!!
Thanks Matthew 🙏😊
You are one of the best teachers. You have your thoughts together, set the agenda and then explained everything is the simplest way possible. Wonderful. Thank you so much.
In my 47 years life journey, Today I Understood some basics in Network IP, Subnet, Gateway. Very good, Neat, decent explanation. THANK YOU THANKING U
Hi, idk if u will ever read this but i just want to say a big thank you for your effort to produce this video. i had a job interview last week and it's an IT related position. My knowledge in IT is not promising but after watching and learning through just this one video overnight, i managed to secure the position at which i explain the network structure mentioned in the video. keep up the good work, because i feel like i have to go back to your videos for other topics in the future :D
Thanks and congratulations brother I am so happy for you. Pls keep supporting and all the best for your career ahead. ☺️🙏
even thought the video was posted 4 years ago it's still very educational and easy to understand. Thank you!
Thankyou 🙏🙏
Stopped the video in modddle to comment this
Frickin Fantasticof you to teach something complex in simple terms..
Thanks Man ♥️
Sir I m from Sri Lanka learning cyber security.This lesson was so interesting and wasnt boring as other courses on you tube + covered all my necessities.Thank you very much♥
Thanks a lot Srilanka is a great place may be I will visit someday
@@ITkFunde sure,Glad to hear😊❤
Just amazing! You took something seen as complex and turned it into a simple, digestible cuisine. You are what I call a master teacher!!! Do you offer online courses? I would love to enroll. Thank you for sharing your gift!
Thank you Wale just doing out of passion but with supporters like yours may be one day I could roll out a course🤓
@@ITkFunde Wow....what an amazing gift. I hope one day you will share it with the world 🙂. The IT world needs such genius in teaching.
@@walesogunro4675 I think he is already sharing it with the world via UA-cam my brother. He is so good! Big ups to you IT K Funde
Thanks brother for your kind words 🙏🙏
18 year old, and learning Audinate Dante networking; this helped more than anyone could imagine
Hello Sir! I would like to tell you that your way of explaining, giving definition and examples are VERY WELL DELIVERED. I EASILY understood each of them. Thank you sir!
Thanks Aaron 🙏☺️
Nice one
Very well explained, watched it repeatedly for a better understanding. Thanks so much. I cannot pay you for this work you do for mankind God only will reward you. Thanks once more and remain bless.
Thanks Uchenna your wishes means a lot to me 🙏☺️
Hey brother. Here in 2024 going through all your content. For a beginner like me, I find your content very simplified and easy to follow. Please keep doing what you are doing.
School ❎ UA-cam ✅
University is just needed for getting Mark's card only not for gathering knowledge.
Now. It's always been.
From indian tech gurus to random useful information provided by the YT algorithm. It's like up-skilling at your own pace.
You are wrong. If this was true people wouldn’t spend lot's of money and time going to school.
@UNMEASURED100 Funny. My professor sent us a link to this video for us to recap for the exam.
This is literally the basics they teach in univ. I think you don't pay attention in classes @@vidyasn4898
Simply amazing. How I wished my first introduction to networking would have been this video. You rock. Subscribed.
Thanks Cassou
wow.... I have been in IT for over 5 years and networking was my weakest point since college. It is the first time I have started to grasp netwroking concepts.
Great teaching style. Subscribed!
finally I understood it completetly because my knowledge in this area was pretty messy . thanks!
Thank you Restilav for your lovely feedback means a lot please keep supporting
i understand this more than my 51 hours college course for this subject
I am just a beginner who wants to learn networking and this video has been made in such away that has really favored me, thanks a lot.
You're very welcome!
am starting on IT and this is wonderful.i
want more
Thanks Samuel
Great work sir. Keep rocking. No textbook or university professor helped me to understand this so easily.
Thanks Sai your feedback made my day !!!
We need more videos on networking
Thanks Tharun for your suggestion I will make more videos
where did you get 255 from? 6:04 can you please inform me?
@@tomross8820 That's the subnet mask. the number of bits in the IP address dedicated to knowing the network address.
I have been learning IT for years. You are the best teacher I've know so far. Thank you for your help.
I was struggling with my classes, and you managed to compress the info into small understandable bites. Thank you so much.
You have to be awarded the prize for the all-time youtube teacher..excellent content and explanations. Thank you
This guy said a family of 500, I'm reading this and it's at 4 million 500 thousand.
Great work.
Thanks Simon 🙏
I have never seen a tutor as good as this dude. Thank you!
Thankyou Ola means a lot 🙏
You did an outstanding job of explaining these concepts! I've been trying to understand networking for years!!!
My god, I bought a 24 hour course, read hunderts of pages for Comptia Network+ and this video explains it so much better in 16 minutes. I subscribed!
♥️♥️ thanks a lot 🙏🙏🙏
Yoh !! I wish I knew this earlier I could have spent all my time learning from a real life situation through the drwaings and things that i have passed through like the school block .Thanks for sharing !!!1

I learn subnet concepts lot. Thanks for simply explained.
Thanks Kailash !!
I am a seasoned learner looking to begin an IT career in Cybersecurity. I wanted to get a jumpstart on IT fundamentals so I am not completely lost. Your visual display, analogies as well as the definitions posted at the top or bottom helped me better understand the content. My IBM cert is self-pace but I know I will be looking for more videos. You are a gem!
Aww they started this video at 500 subscribers 9 months ago?? Now at 61,000♥️♥️the growth!👏🏾👏🏾🙌🏾

When i saw it first time..ie now it stands at 1 lakh
I was so in need of this explanation. I realize that this video is a couple a years old, but still is some to learn from. Thanks gentlemen for making this possible!
such an amazing lecture...........this is not only learning its also motivating us to keep going and learning networks....thank u Sir...stay home and stay save...
Thanks Kaafi 🙏☺️
Absolutely fantastic, simple but to the point. Excellent job well done. A master piece. Thank you so much for putting everything together in just one simple video.
Thanks 🙏🙏
This is the first time I stumbled on your page. I have watched it several times. You made it so simple that it’s so easy to comprehend. Thank you.
that was a great explanation!!!!!!!!!!the analogy made it easier to understand the concept. Thank you Mister
Thanks Monique
The approach to explain the bits & bytes of networking is really awesome.. Very simplistic yet great analogy to make the concept lucid & understandable.
Thanks for all your hardwork👍👍would highly appreciate if you demonstrate the lab also on port forwarding & NATTING... This would atleast give the better visualization here in these last two concepts👏👏
Thanks Nirabh I have put up a networking playlist pls chk if that helps

Thank you very much Sir for easy to comprehend explanation. I'm 56 and started a new journey as an IT student. Very grateful that I've found your channel. You are a gifted teacher and please continue to inform.
You really got the grace of explaining the terms so clear and concise.
Thanks Reshak
Thank you! 1st video I've seen that ties everything together simply. Amazing!
THANK YOU SO MUCH!!!
I got a 90 out of 100 points on my presentation at school due to your video. My group had to make presentation about different OS components for example: secondary storage, I/O System, File Management etc. and I had the topic networking and your Video helped me so much. Thanks
Thanks and congratulations
i would like to say thank you for explaining in a way even a non i.t background like myself can understand, i'm currently taking network admin course and i admit it's really overwhelming. transitioning is not easy. i hope you guys do other videos like security+ course. i rarely leave a comment but for you guys, really appreciate the vid tutorials.
Thank Anshul Tiwari.
Remain blessed.
I need on cybersecurity as well
Thanks Dianne, for your lovely comment, its a solo show that i run on weekends outside my normal job sontry to share whtever i can but will keep adding more useful content ❤️
You're just amazing.. So simply u made us understand the concept.. Thank u
Thanks Desta
Bro said, family of 500 and thanked everyone who subbed to him. 4 years later he is about to hit 500K subs. Time sure does magic! Keep it going lil bro!
Thanks Bhai ❤️
Extremely marvelous .I love the way the practical explanations always comes before the definitions . They make your explanations clearer and easier to understand
Thanks Priscilla ♥️☺️
You have my respect friend. This was a fabulous video. Thank you! :)

Thanks Moh 🙏
Awesome ways of teaching honestly, thank you so much, this made everything so much clearer!
Thanks loni☺️
Hi
I am an IT apprentice, who feels like they have no clue what I am doing atm. Going through training at work and learning basic networking stuff and it doesn't make sense to me.
This video has helped me learn some new stuff. Thankyou so much!
