Lesson notes
Explain why networks use layers and map OSI's 7 layers to the TCP/IP model's 4 layers
Key points
- TCP/IP has four layers: Link, Internet, Transport, Application.
- OSI layers 5, 6 and 7 all collapse into the TCP/IP Application layer.
Takeaway: OSI layers 5-7 become the single TCP/IP Application layer.
Quick check: OSI Session, Presentation and Application layers map to which single TCP/IP layer?
- Transport
- Application
- Internet
Top three OSI collapse up, bottom two OSI collapse down: 3-1-1-2.
