idea solution:
OSI model was created by Advance research project agency (ARPA) but after the advent of the Internet, there arose the need for a streamlined protocol suite so the Defense Advanced Research Project Agency (DARPA) decided to create the TCP/IP protocol suite. Prior to discussing which model is best let’s have a comparison of both of these models Sr.
No. TCP/IP Reference Model OSI Reference Model
1 Defined after the advent of Internet Defined before advent of internet
2 Service interface and protocols were not clearly
distinguished before
Service interface and protocols are
clearly distinguished
3 TCP/IP supports Internet working Internetworking not supported
4 Loosely layered Strict layering
5 Protocol Dependent standard Protocol independent standard
6 More Credible Less Credible
7 TCP reliably delivers packets, IP does not
reliably deliver packets All packets are reliably delivered
The entire communication industry stands on the backbone of TCP/IP and OSI reference model.
As for as we discuss which model is best it depends on what we are working with. In the networking field, the TCP/IP model is more relevant. However, in other computing fields such as programming, the OSI model would be better suited.
………………
OSI and TCP Ip model are contrary both models has there own important and without any model (TCP/IP or OSI) the communication is not necessary just take a look that OSI model play role in computer it works between application layer to physical layer or physical layer to application layer after this process osi model completes its step than TCP/IP model starts it work it start from the communication from source mac address to destination mac address where TCP/IP (Private and Public IP ) plays there role so it clear that no model is best than other both works in there manner
