Mastering the Concepts of OSI Model
What you'll 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
Requirements
