differences between OSI and TCP/IP reference models? Explain briefly. The main differences between the two models are as follows: - - OSI is a reference model and TCP/IP is an implementation of OSI model. - TCP/IP Protocols are considered to be standards around which the Internet has developed. The OSI model however is a “Generic‚ protocol-independent standard." - TCP/IP combines the presentation and session layer issues into its application layer. - TCP/IP combines the OSI data link and
