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.
