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.

These are the guys who used to help their friends to clear exams by explaining concepts to them, just minutes before entering exams halls. 😁

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!

[pattysplayhouse]

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!!

[nomadicnihal]

THIS IS WHAT A LEACTURE IS EXACTELY CALLED
THANKS A LOT SIR.

[sunilaigal]

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.

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!!

[moonlight_sisterz]

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.

[carloslao]

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!

[isaiasromo]

Been doing networks for a long time and this right here is one of the best explanations I've come across on YouTube. I was curious what you had to say and this is good even for the most seasoned engineers. Keep up the good job.

[justinb]

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!

[VanjaStojanovic]

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.

[MySangakkara]

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😊.

[jaud]

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.

[andrecrisley]

This helped me a lot. I was struggling to understand the Network Technologies lecture today. Thanks a million.

[chitra]

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. ✌👍👏

[taylorscott]

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!

[theresanoelle]

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

[ZenozaProject]

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!
