In OSI model there are 7 layers but in TCP/IP there are 4 layers The application layer in TCP/IP handles the responsibilities of layers 5, 6 and 7 in the OSI model. The transport layer in TCP/IP does not always guarantee reliable delivery of packets at the transport layer, while the OSI model does. TCP/IP also offers an option called UDP that does not guarantee reliable packet delivery. Attempts tests for proper preparation available @ http://www.tcyonline.com/tests/osi-and-tcp
