Learn computer network layers or OSI layers in a computer network, OSI Model, OSI reference model or open system interconnection model or networking model including Application Layer, Presentation Layer, Session Layer, Transport Layer, Network Layer, Data Link Layer and Physical layer. Definition, Function, and use of the OSI network model. Protocols in computer network layers of OSI model.
OSI Model defines and is used to understand - How data is transferred from one computer to another in a computer network?
In the most basic form, two computers (end-points) connected to each other with LAN Cable (Network Media) and connectors (RJ45) sharing data with the help of NICs forms a network.
But if one computer is based on Microsoft Windows and the other one has MAC OS installed, then how these two computers are going to communicate with each other?
In order to accomplish successful communication b/w computers or networks of different architectures, 7-layered OSI Model or Open System Interconnection Model was introduced by the International Organization for Standardization in 1984.

I don't usually comment on videos like this, however I'm going to make a massive exception in this case. Made over 4 years ago, this video is still relevant, informative and very simple to understand. I'm currently writing a report for my uni assignment and this has by far been the most useful source of usable information I have found. Absolutely impressed with the delivery of information in this video. Not only was I able to write my assignment with ease, but I've also been able to learn a lot, and more importantly understand the way data transfers from one computer to another, in extensive and simple detail. Thank you!

@farooqabbasabbas8322 Год назад

@miennai9448 Год назад

The best OSI model video so far. Also the only one I've seen that had the sense to talk about the model from the 7th layer down. Every other video insisted on starting from the 1st layer, which would force them to talk about how data from a higher layer is handled, before actually talking about that higher layer. Your way is far more understandable.

if you still do not understand OSI model and TCP/IP model after watching this video, forget it. This is the best explanation you will get in the world. Its like he is the one who developed the conceptual framework back in 1980. I also realised its a bad idea to try learn OSI model if you dont fully understand how the switch and router work.
