same:
- they are layer protocol
- they all have application, transport, and network(internet) layer.
- the layer above tranport layer are application
difference:
- OSI has 7 layers, but TCP/IP has 4 layers
- OSI differentiates service, interface, and protocol, but TCP/IP does not.
- the Host-to-network is not a layer, it is an interface between datalink layer and network layer.
- the TCP/IP only has connectionless in internet layer, but OSI has connectionless and connection oriented in network layer.
- the TCP/IP has connectionless in tranport layer, but OSI only has connection oriented in transport layer.
