What is the difference between TCP/IP model and the OSI model?
Following are the differences between the TCP/IP model and OSI model:
| TCP/IP model | OSI model |
|---|---|
| Full form of TCP is transmission control protocol. | Full form of OSI is Open System Interconnection. |
| TCP/IP has 4 layers. | OSI has 7 layers. |
| TCP/IP is more reliable than the OSI model. | OSI model is less reliable as compared to the TCP/IP model. |
| TCP/IP model uses horizontal approach. | OSI model uses vertical approach. |
| TCP/IP model uses both session and presentation layer in the application layer. | OSI Reference model uses separate session and presentation layers. |
| TCP/IP model developed the protocols first and then model. | OSI model developed the model first and then protocols. |
| In Network layer, TCP/IP model supports only connectionless communication. | In the Network layer, the OSI model supports both connection-oriented and connectionless communication. |
| TCP/IP model is a protocol dependent. | OSI model is a protocol independent. |
