🌐 Cyber Cert CAP Seminar – Week 2, Friday

Focus: OSI → TCP/IP Model + Networking Commands

Learning Intention

We are learning how to map OSI to Cisco’s TCP/IP model and use basic commands to test connectivity.

Success Criteria

• I can match OSI layers to TCP/IP layers and run at least 3 commands for network testing.

📝 Study Notes

OSI (7 layers) → TCP/IP (4 layers)

• Application = Application, Presentation, Session
• Transport = Transport
• Internet = Network
• Network Access = Data Link + Physical

Key Networking Commands:

• ping – test connectivity.
• ipconfig / ifconfig – view IP address.
• tracert / traceroute – trace route packets take.
• nslookup – test DNS resolution.
• netstat – view active connections.
