UDP and TCP both are transport layer protocols. UDP is connection less and TCP is connection oriented. UDP is preferred over TCP when large amount data is to be sent like on skype or video conferencing .
TCP/IP because the osi model has seven layer but in tcp/ip only four layers and most important is that the tcp/ip model is reduce the function of osi model.
The OSI model encompasses all of the TCP/IP sub-protocols plus several other protocols that are not part of TCP/IP. These would include IPX/SPX, NetBEUI, Appletalk, and other proprietary protocols that are not part of the TCP/IP model.

1.The OSI model originally distinguishes between service,interval and protocols. 1.The TCP/IP model doesnt clearly distinguish between service,interval and protocol. 2.The OSI model is a reference model. 2.The TCP/IP model is an implementation of the OSI model. 3.In OSI model,the protocols came after the model was described. 3.In TCP/TP model,the protocols came first,and the model was really just a description of the existing protocols. 4.In OSI model,the protocols are better hidden. 4.In TCP/IP model ,the protocols are not hidden. 5.The OSI model has 7 layers. The TCP/IP model has only 4 layers. 6.The OSI model supports both connectionless and connection-oriented communication in the network layer,but only connection -oriented communication in transport layer. 6.The TCP/IP model supports both connectionless and connection-oriented communication in the transport layer.,giving users the choice.

layered model architecture is tcp/ip model .you can reference this model as layered model architecture protocol.

Offcourse osi..... TCP/IP is an implementation of osi....
The OSI model came after TCP/IP networking protocols were available in networks. The OSI description also as to describe and identify networking components that do not exist in the TCP/IP model.
FTP uses TCP, which uses IP
