Comparison between OSI and TCP/lP model:

OSI	TCP/lP
OSI provides layer functioning and also defines functions of all the layers.	TCP/IP model is more based on protocols and protocols are not flexible with other layers.
In OSI model the transport layer guarantees the delivery of packets	In TCP/IP model the transport layer does not guarantees delivery of packets.
OSI follows horizontal approach	TCP/IP follows vertical approach.
OSI model has a separate presentation layer.	TCP/IP does not have a separate presentation layer.
Network layer of OSI model provide both connection oriented and connectionless service.	The Network layer in TCP/IP model provides connectionless service.
OSI model has a problem of fitting the protocols in the model	TCP/IP model does not fit any protocol
Protocols are hidden in OSI model and are easily replaced as the technology changes.	In TCP/IP it is not clearly separated its services, interfaces and protocols.
OSI has 7 layers	TCP/IP has 4 layers
