What You Will Learn!
- Understand the OSI (Open Systems Interconnection) model as a conceptual framework for understanding network communication.
- Learn the seven layers of the OSI model, including Physical, Data Link, Network, Transport, Session, Presentation, and Application layers.
- Gain in-depth knowledge of the functions, protocols, and technologies associated with each OSI layer.
- Explore practical applications of the OSI model in real-world networking scenarios.
- Master troubleshooting techniques using OSI layer concepts to diagnose and resolve network issues.
- Gain hands-on experience through lab exercises, simulations, and case studies to reinforce theoretical knowledge.
- Develop critical thinking skills to analyze network architectures and design solutions using OSI layer principles.
- Learn about the OSI model's relationship with the TCP/IP model and other networking standards.
- Understand the advantages and limitations of the OSI model in modern network design and implementation.
- Prepare for industry certifications, such as CompTIA Network+, Cisco CCNA, or other networking certifications that require a strong understanding of the OSI mod
Description
In this course, you learn about the basics of network communication. All about how the data is transferred on the network and logical addressing to communicate on the network. Dhananjay has tried demystifying the concepts of network communication through the 7 layers of the OSI model.
