Hi Friends, I am Anshul Tiwari, and welcome to our youtube channel ITkFunde.

More about this video -
In this video, we will learn the fundamentals of the OSI model. Open System Interconnect (OSI) model is a framework that divides all network communication into 7 distinct layers. Each layer has a specific role to play in network communication.

These 7 layers (from bottom to top) are: -
1. Physical
2. Data Link
3. Network
4. Transport
5. Session
6. Presentation
7. Application

So in this video, we will learn the very basics of osi model using a real-life example and understand how a sender sends and the receiver receives the data via the network.

Also, we will understand what are Protocol Data Units (PDUs) and how data changes while it flows through each layer of osi model. We will also know the famous protocols of each layer like http, ftp, smpt,tcp, udp,ip etc. We will come to know which device falls into which layer like routers, firewalls, VPNs, proxies, etc.

At the end, we will learn the basic difference between osi and tcp/ip model. Hope this video gives you a new perspective of learning the osi model.

I have been in IT Industry for over 25 Years, more than a decade of teaching experience but I couldnt expain better than this guy, hats off man you are doing good job keep it up, always deliver new technolgies.

[kabeermirza]

This man is on another level of teaching. Like before this video I was completely a newbie, but after watching this video my way of thinking completely changed on how our data is transferred from one place to another.

Edit: I've passed my CCNA 200-301 on the first go. To the guys out there who also want to earn this certification, My man will help you get your base stronger as it is the most important part of starting something from scratch.

I am glad you decided to take on that task for the OSI model. You are one of the best teachers I have seen for these subjects. Makes it fun, interesting and relatable. Amazing work.

[pralaynathgendaswamy]

The amount of effort you put in, complemented by your level of knowledge and understanding, is clearly remarkable. Not to mention that anyone hardly cares about trivial details such as light exposure, etc. when they have some quality stuff that keeps them glued to the screen. Thank you so much!

I just subscribed to your channel. I remember learning this back in 2006, just got promoted to a PC System Administrator and needed a refresher. The way you explain and teach in Layman's terms is a genius. I understood it technically but never fully grasped the understanding and applying it to a real world situation. Keep up the Great work!

[TouchNetXD]

omg, this guy is the best he has a huge ability to explain things!!!

[pravingate]

This video saved my more time in understanding same concept with reading books.. thanks for making such video's on basic concepts..

[komalsingh]

No body ever taught OSI Model this way. This was so nicely articulated. Thank you so much :)

[michaeljohn]

Just starting my career in cybersecurity, thank you very much for this awesome video!

[AlejandroGarcia-temm]

I'm just a computer engineering student getting into computer networks and after reading the ISO/IEC 7498-1 and watching a lot of videos about the OSI Model all I can say is this is beautifully explained. Thank you.

[mugisharichardstone]

The most excellent presentation on OSI Model, that I have seen in my more than 10 years of IT profession experience. I immediately subscribed hahahahaha

[ebubefelix]

I got hooked from one video, and this made me furious with my lecturers just handing out notes and teaching trash!! .... Well-done, keep it up, best learning process I've undergone in a while.

[spurshlaserclinc]

Hi, your videos are such a easy way to understand and realy realy helpful. Thanku somuch

[topvidz]

You did an amazing job in explaining the network layers. This is the first time I am able to understand the concept clearly. Thank you!

[JayaLakshmi-zrrz]

Your way of delivering the topic is amazing. The analogy u drew between the layers n army ranks was superb. I many a times read books to understand this OSI layers but it is your lecture that helped me in remembering the layers n functions of each, all in one shot. Thanku

[robertroy]

Impressive. I've watched a lot of videos about the OSI 7 layer model. This one is the best.

[BKL]

Wow !!! I am just a beginner, had tried other videos with millions hits, but could hardly understand what I really wanted to understand . Saw one of the video of this channel and then followed it up with this one and I must say now I want to learn my networking from here only . Respect sir 🙏

[nemeziz_prime]

Really loved this explanation. Really amazing teacher !!! Wish we had such creative teachers in college

[kalyanisrivastva]

You have taught me, what 4 years of college couldn't!!! Thank god you made a youtube channel! THANK YOU SO MUCH💐🥇

[kevinwinters]

WOW! I have learned more from watching two of your videos than from almost 10 years in IT! I am so excited to keep learning from you! I am a new subscriber
