Below are elements which differeciate between OSI Layer and TCP/IP Layers, EXCEPT

• OSI Model has 7 Layers, TCP/IP has 4 layers

• OSI model has a problem of fitting the protocols into the model, whereas TCP/IP model does not fit any protocol

• Transport Layer in OSI model is Connection Oriented, but in TCP/IP model is both Connection Oriented and Connection less.

• In OSI model the transport layer does not guarantees delivery of packets, In TCP/IP model the transport layer guarantees the delivery of packets.
