Comparison of OSI V/s TCP/IP reference model?

Will you be kind enough to explain what is vertical approach in OSI and horizontal approach in TCP/IP along with some other comparison points ?

According to wiki, TCP/IP is mostly used but why as the transport layer do not guarantees delivery of packets and provides connection less service ?

What is meant by "OSI developed model then protocol whereas TCP/IP developed protocol then model " ?

 

Thanks in advance

For your understanding refer OSI model as in real time also OSI is used.

TCP/IP was the refrence model from which OSI was made.

OSI(Open System Interconnection)/////TCP/IP(Transmission Control Protocol / Internet Protocol)

1. OSI is a generic, protocol independent standard, acting as a communication gateway between the network and end user.1. TCP/IP model is based on standard protocols around which the Internet has developed. It is a communication protocol, which allows connection of hosts over a network.

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

3. Follows vertical approach.3. Follows horizontal approach.

4. OSI model has a separate Presentation layer and Session layer.4. TCP/IP does not have a separate Presentation layer or Session layer.

5. OSI is a reference model around which the networks are built. Generally it is used as a guidance tool.5. TCP/IP model is, in a way implementation of the OSI model.

6. Network layer of OSI model provides both connection oriented and connectionless service.6. The Network layer in TCP/IP model provides connectionless service.

7. OSI model has a problem of fitting the protocols into the model.7. TCP/IP model does not fit any protocol

8. Protocols are hidden in OSI model and are easily replaced as the technology changes.8. In TCP/IP replacing protocol is not easy.

9. OSI model defines services, interfaces and protocols very clearly and makes clear distinction between them. It is protocol independent.9. In TCP/IP, services, interfaces and protocols are not clearly separated. It is also protocol dependent.

10. It has 7 layers10.

It has 4 layers

Whoops, looks like something went wrong.
