OSI and TCP/IP Network Models Explained

In this video, I break down the OSI and TCP/IP network models to help you understand how data travels across networks. Learn the structure, functions, and differences between these two foundational models, and see how they apply to real-world networking and troubleshooting. Whether you’re just starting or deepening your network knowledge, this video will provide you with essential insights into how networks operate at each layer, from physical transmission to application protocols. Key Takeaways: - OSI Model: 7 layers of network communication, from physical transmission to application protocols. - TCP/IP Model: A simplified, practical approach used in most modern networking. - Real-world troubleshooting strategies based on these models. #itcareer #realtech #cloud #interview #technology #networkadmin #networkadmin #networkadministration #osi #tcpip #networkmodel #osimodel #tcpipmodel #devops #devopstrainingvideos 00:00 Introduction 00:29 Please support this channel via Like and Subscribe 00:45 OSI Model 01:21 Physical Layer 01:55 Data Link Layer 02:21 Network Layer 02:49 Transport Layer 03:20 Session Layer 03:47 Presentation Layer 04:14 Application Layer 04:36 TCP/IP Model 04:58 Link Layer 05:11 Internet Layer 05:26 Transport Layer 05:39 Application Layer 05:58 OSI vs TCP/IP Models 06:20 Practical Usage of these Network Models
