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.
