TCP/IP model is defined with 5 layers as application layer, transport layer, network layer, data link layer and physical layer. The four layer TCP/IP model has the layers Application Layer, Transport Layer, Internet Layer and Network Access Layer.
OSI 7 Layers Model
- Physical Layer.
- Data Link Layer.
- Network Layer.
- Transport Layer.
- Session Layer.
- Presentation Layer.
- Application Layer.
The presentation layer prepares data for the application layer. The application layer is used by end-user software such as web browsers and email clients.
5 Network Layers
Tenendo conto di questo, what are the 5 network layers? The TCP/IP model is based on a five-layer model for networking. From bottom (the link) to top (the user application), these are the physical, data link, net- work, transport, and application layers. Not all layers are completely defined by the model, so these layers are “filled in” by external standards and protocols.
