6. 0 2006 2 1 22 TCP IP Even though Ethernet and TCP IP are often used together and sometimes used interchanged these are three different kinds of terms and you should carefully separate them The coherences are based on the ISO OSI reference model after ISO IEC 7498 that is needed to basically understand these terms Ethernet only describes layer 1 and 2 in this model nevertheless the term is often used in error in engineering as description of all layers between 1 and 7 The IP protocol of layer 3 was developed in the 70 s by the US military MIL STD 1777 It allows a universal addressing inde pendent of the hardware involved in heterogeneous networks It also manages the transfer of large packets by splitting them up into smaller packets The well known TCP protocol MIL STD 1778 ensures a reliable data transfer Http RFC 2068 and SMTP MIL STD 1781 belong to layer 7 of the OSI model and allow to transfer data and documents via web browser or to send e mails UDP IP User Datagram Protocol is utilized to send data that does not need to be transferred in a reliable way The UDP packet is en capsulated in an IP packet which in turn is encapsulated in a PPP packet Both UDP and IP have checksum octets and the PPP packet has its FCS octets however this can only guarantee that the data and the destination are correct If a packet is lost it will not be resent using UDP this issue is only addressed by the TCP protocol Ha
