Difference between OSI and TCP/IP reference model

Updated on June 18, 2013

OSI

1)It has 7 layers

2)Transport layer gurantees delivery of packets

3)Horizontal approach

4)Separate presentation layer

5)Separate session layer

6)Network layer provides both connectionless and connection oriented services

7)It defines the services,interfaces and protocols very clearly and makes a clear distinction between them

8)The protocol are better hidden and can be easily replaced as the technology changes

9)OSI truly is a general model

10)It has a problem of protocol filtering into a model


TCP/IP

1)Has 4 layers

2)Transport layer does not gurantees delivery of packets

3)Vertical approach

4)No session layer, characteristics are provided by transport layer

5)No presentation layer, characteristics are provided by application layer

6)Network layer provides only connection less services

7)It does not clearly distinguishes between service interface and protocols

8)It is not easy to replace the protocols

9)TCP/IP can not be used for any other application

10)The model does not fit any protocol stack.
