OSI model vs TCP/IP Model

OSI model vs TCP/IP Model

Hello, guys‌Ever you read the OSI model vs TCP/IP model with full detail. But if anyone asks you simply that what is the difference between OSI model & TCP/IP model? Maybe you have only one or two difference like OSI have 7 layers and TCP/IP have 4 layers. but that type of answer like a schoolboy, not a network guy. An interviewer asks mostly that question. So, now I writing about the difference between OSI model & TCP/IP model.

OSI model vs TCP/IP Model ( Comparison ) In the OSI model for delivery of packet must be guaranteed by the transport layer.

In TCP/IP, no one layer takes guarantee like the OSI model but still more reliable than the OSI model.

OSI model in which layer 3 (network Layer) gives two services – connection-oriented & connectionless.

TCP/IP in which the Internet layer provides only connectionless service.

OSI model work as a guidance tool.

TCP/IP like some part of the OSI model.

OSI model some problem face to fit out side protocol.

Separately Can not fit any Protocol in the TCP/IP model.

OSI model has strict Boundaries. It follows the vertical approach.

TCP/IP does not have. It follows the horizontal Approach.
