Exam Tips - TCP/IP Layers
Key facts to memorize:
- 4 layers: Application, Transport, Internet, Link (top to bottom)
- Application: HTTP, SMTP, FTP - what you interact with
- Transport: TCP (reliable) or UDP (fast) - error checking
- Internet: IP addresses, routing
- Link: MAC addresses, physical transmission
- TCP vs UDP: TCP=reliable (checks errors), UDP=fast (no checking)
Perfect exam answer:
"Describe the four layers of the TCP/IP model" (4 marks):
Application: Network services/protocols like HTTP (1 mark).
Transport: Reliable delivery using TCP/UDP (1 mark).
Internet: Routing using IP addresses (1 mark).
Link: Physical transmission over network hardware (1 mark).
