- Network communication is structured into layers, each performing a specific functions and passes data to the next layer.
- Layering simplifies network design, helps isolate problems, and allows different technologies to work together. For example:
- Application layer uses protocols like HTTP, FTP, SMTP.
- Transport layer uses TCP to ensure reliable communication.
- Internet layer uses IP to route data.
- Network access layer handles physical transmission (Ethernet, Wi-Fi).
