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 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.

@kabeermirza055 3 года назад

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.

@pralaynathgendaswamy8662 Год назад

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!

@komalsingh9467 Год назад

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

@omari6184 3 года назад

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!

@trenholmelodge1820 2 месяца назад

this is the most specific and understandable video on how the OSI model works that I have seen. It gets away from the 'abstract" explanation that most presenters use to explain and show the actual sequence of events and what specifically happens at each level/. thank you so much will watch your other videos.
