DIFFERENCE BETWEEN OSI AND TCP/IP MODEL

Difference Between OSI AND TCP/IP Reference Model

         OSI  MODEL   

1. OSI is a generic protocol independent standard, acting as a communication gateway between the network and end user.                         

                                                        

2. In OSI MODEL the transport layer guarantees the delivery packets.                   

3. Follows vertical approach.                                   

4.OSI MODEL has a separate Presentation layer and Session layer.                       

5.Transport layer is a connection Oriented.    

               

6.Network layer is both connection Oriented  and connection less.

TCP/IP MODEL

1.TCP/IP model is a based on standard protocol around which the internet has developed.          It is a communication protocol  which allows connection of hosts a network.

2.In TCP/IP MODEL the transport layer does not guarantees delivery of packets. Still the TCP/IP model is more reliable.

3.Follows horizontal approach.

4.TCP/IP does not have a separate  Presentation layer and Session layer.

5.Transport layer is both connection Oriented and connection less.   

6.Network layer is connection less.
