- The TCP/IP Network Model is a layered model that describes how networks and internetworking work.
- The model separates functions into four layers
- Application Layer
- Transport Layer
- Internet Layer
- Network Access Layer
- Each layer is independent of the layer above it and below it and the layers don't need to know how the layer operates.
The TCP/IP Network model is covered on the Cisco Certified Network Associate (CCNA), CompTIA Network+ and other certification exams.
