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?
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 😁
School ❎ RUclips ✅
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.
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
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
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
ruclips.net/video/q1Qjn6QV7tU/видео.html
Well said 👏
He's the only teacher u can understand even when is speaking a different language
thanks Sunil ❤️
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!!
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 ?
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.

I wish I had you as my Math Teacher when I was at school! You reflect what all teachers should be! Subscribed.
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!
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!
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 !!!
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
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 ☺️
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
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.
Been doing networks for a long time and this right here is one of the best explanations I've come across on RUclips. 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 ❤️
I never ever comment on RUclips 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.
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 🙏
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🙏☺️
Thank you for your time making this video. I was doing some research on a company that was publicly traded and wanted to have an insight on what the business was about. You broke this down so perfectly with the school analogy. Thank very much !
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 🙏❤
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 🙏😊
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 working towards my cybersecurity bachelor's degree and this video finally got me to understand subnets. Thank you, you're an excellent teacher!
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
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 RUclips 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❤️
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 .............
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
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
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 RUclips. No question. Thanks again.
Thank you Jim 🙏🙏☺️☺️
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 🙏
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 ☺️☺️♥️
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!
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.
I was struggling with my classes, and you managed to compress the info into small understandable bites. Thank you so much.
Thank you so much for this very clear explanation of networking basics! I’m considering pursuing a networking career change, but don’t know anything about it; of course, there’s still very much to learn, but you have made the networking monster seem a little smaller and more understandable!
I used to teach kids to design this on a Boson Simulater by the end of the semester , way back in 2005 and 2006
definitely taught them applied Network Engineering , rather than sticking to the Course book , dull and drab details of Algorithms already being used in Market.
they had hands on experience on seeing how thier network was working with Different protocols.
Man... I never saw anyone explain so simply yet so clearly....you have my deep respect..and I'm grateful for the AMAZING content
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 is hands down the best beginner friendly introduction to networks I've found. Thank you so much.
watched the first 9 minutes and i already learned a lot compared to some paid courses who just lay all the terminologies down and vague definitions. Big respect to you sir
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
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!
You just broke that all the way down in the layman terms. Thank you sooooo much.
You did an outstanding job of explaining these concepts! I've been trying to understand networking for years!!!
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
Excellent presentation, precise points, and NO drama dialogues. simple straight to the point !!
You are the best teacher; the way you described everything was incredible. I am a huge supporter of your efforts to educate the public.
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 🙏☺️
You have to be awarded the prize for the all-time youtube teacher..excellent content and explanations. Thank you
Ive be en watching a couple of videos lately and many instructers but this was by far the best. I will definitely be excploring your channel for more and better learning. thankyou
Best explanation of a Network I have ever heard! I'm a chemical engineer, and I have heard this type of explanation before, but it never got through to me. Thank you very much!
Thank you! 1st video I've seen that ties everything together simply. Amazing!
that was a great explanation!!!!!!!!!!the analogy made it easier to understand the concept. Thank you Mister
Thanks Monique
This guy breaks everything down into very simple concepts. Loooove his content.
Could you please make an entire playlist on Networking, its basics and fundamentals?
You’ve explained everything in a very simplified way, which is extremely helpful for those who are just getting a hold of Networking in general, thanks a lot!
I agree. He should look into. Even explain it better than Professor messer or Dion
You have my respect friend. This was a fabulous video. Thank you! :)
Thanks Akshay for ur support 🙏🙏
Aww they started this video at 500 subscribers 9 months ago?? Now at 61,000♥️♥️the growth!👏🏾👏🏾🙌🏾
Thanks Danielle 🙏☺️
Now 78.1k🔥🔥❤️
@@ITkFunde of course!! Congratulations!!
Now 90.1k😎🔥
When i saw it first time..ie now it stands at 1 lakh
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 🙏🙏
Absolutely brilliant illustration! I never would have thought I'll learn this in just 14 minutes, 57 seconds.
Thank you so much.
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 ❤️
Simply amazing. How I wished my first introduction to networking would have been this video. You rock. Subscribed.
Thanks Cassou
Inorder to change my domain, I've started searching on youtube, and it's really a great start, Thanks man!!!
Man, you are an effective teacher. Taking a mattter and explaining it as simple as possible such that you understand it immediately. Fantastic work.
Thanks ❤️❤️🙏🙏
Just in case someone comes to the comments to understand NAT. NAT is the process of translating private IPs to public IPs and vice-versa. We consider the machines in our LAN to have private IPs (typically identifiable because they start with 10..., 192..., 172.. I think). Private IPs are not exposed to the Internet. This is used mainly for lack of unique public IPs available and for security purposes.
Thanks Guillermo for your contribution 👍
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
You're an excellent teacher. You made these concepts seem so simple, unlike pretty much every other video I've watched. Subscribed!
thanks Brandon
I have never seen a tutorial with exact and very clear information about networking foundations 💯👏
I learn subnet concepts lot. Thanks for simply explained.
Thanks Kailash !!
Awesome works dude, u make our technological field interesting and lovable by the upcoming and young generations,way to go.
The analogies are to another level of comprehension of the subject matter and content.
Thumbs up for you
Very easy to understand, I love the explaining method.
some people just make it so complicated and you find it boring. Thank you so much.
Good job explaining this information. I have 34 years experience in Telecommunications and some IT . This is a very good illustration and easy to understand.
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
ruclips.net/p/PLcnJIHtHiTA0C9UXgU2C6eTQMVFzSlIdP
You're just amazing.. So simply u made us understand the concept.. Thank u
Thanks Desta
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
In 14 minutes I understood basics of networks, wonderful explanation sir thanks for helping !
You truly have a gift for teaching! Great job, thanks relating networking to something many of us understand.
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.
It's astonishing how good you are at the art of teaching. Thank you so much.
something a teacher explained for an hour, you explained it all in just 14mins. very well explained and very informative video
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. ☺️🙏
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 have been studying networking basics for some time but could not understand after listening to your teaching I know much about networking, you are really a good teacher.
I really dont have words to define my happiness after listening to your explaination Sir. This is what I was looking for. We can clearly understand your intention of sharing the knowledge in your body language. Long live Sir. May God bless you in every step you take in your life. Love your teaching Sir.
Good one, it explains precisely about LAN & WAN within d short duration!!
Thanks Dinabandhu !!
I finally understand subnetting. Thank you!
Thanks Moh 🙏
I am 62. I clearly understood everything that you said. Thank you so much for the clear and slow explanation
This video is helping me understand better Networking after not touching it for over a year. Thank you so much
am starting on IT and this is wonderful.i
want more
Thanks Samuel
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!

I LEARNED MORE IN THIS 15 MINUTES ABOUT NETWORKS THAN IN 4 YEARS OF COLLEGE, THANK YOU SO MUCH SIR!!! I JUST SUBSCRIBED! IM TRYING TO BREAK INTO CYBERSECURITY, HAVE NO EXPERIENCE, ANY ADVICE WOULD BE GREATLY APPRECIATED!! THANKS AGAIN!!
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 🙏☺️
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 🙏☺️
thank you king. it's nice to get a networking basics guide for those of us that are not professionals but wish to improve our home setup with understanding.
Thank you for this video, I am just preparing for my networking concepts class that's starting pretty soon and watching this video made me understand and prepared on what I will be facing on and such. Wish me luck...
