popularprotocol stack for wide area networks. It is commonly known as TCP/IP‚ because of its most important protocols: Transmission Control Protocol(TCP) and Internet Protocol (IP)‚ which were the first networking protocols defined in this standard. It is occasionally known as the DoD model due to the foundational influence of the ARPANET in the 1970s (operated by DARPA‚ an agency of the United States Department of Defense). TCP/IP provides end-to-end connectivity specifying how data should be formatted

parts of TCP/IP and what do they do? Who is the primary user of TCP/IP? TCP/IP is the transport/network layer protocol we use on the internet. Many BN’S‚ MAN’s and WAN’s rely on it. This is because it is relatively efficient‚ and transmission has few errors. Any errors that are found‚ are checked and so large files can be sent even in the most unsafe network and the data will still be unchanged. TCP/IP is very compatible with a number of data link protocols as well. The two parts of the TCP/IP are

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
