Difference between osi and tcpip model?

The main differences between the two models are as follows:

1.OSI is a reference model and TCP/IP is an implementation of OSI model.2.TCP/IP Protocols are considered to be standards around which the internethas developed.The OSI model however is a "generic, protocol-independent standard."3.TCP/IP combines the presentation and session layer issues into itsapplication layer.4.TCP/IP combines the OSI data link and physical layers into the networkaccess layer.5.TCP/IP appears to be a simpler model and this is mainly due to the fact thatit has fewer layers.6.TCP/IP is considered to be a more credible model- This is mainly due to the

fact because TCP/IP protocols are the standards around which the internet

was developed therefore it mainly gains creditability due to this

reason. Where as in contrast networks are not usually built around the OSI

model as it is merely used as a guidance tool.

7.The OSI model consists of 7 architectural layers whereas the TCP/IP onlyhas 4 layers.

8.The TCP/IP design generally favors decisions based on simplicity,

efficiency and ease of implementation
