networking models are TCP/IP which had 5 different layers and the OSI model which has 7 layers. They mainly incorporate the same layers and the only difference is that the TCP/IP layer combines layers 5‚ 6 and 7 all into layer 5. Both models are along the same line of information and both explain how a network moves data. 3.2: OSI reference model: The OSI model includes two more layers that the TCP/IP layer already had but is constructed in only layer 5. 7: Application Web browser‚ 6: Presentation

Application Layer (7) This layer represents the various network applications such as e-mail reader‚ Web browser‚ Hypertext Transfer Protocol (HTTP)‚ File Transfer Protocol (FTP)‚ and Network File System (NFS). ✦ The application layer provides a user interface and processes network data. ✦ The application layer on the sending host produces the network data to be transmitted from the sender host. ✦ The application layer on the receiving host consumes the network data produced and transmitted

transmitted. Data communications is a subset of telecommunications. Data can include or convey graphic images‚ sound‚ or video files. The physical layers of the OSI and TCP/IP models are very similar. The data communications phase associated with digitization is the first phase. The portion of an IP address from which bits are borrowed when sub netting is the host. The transport layer ultimately passes data up to the application layer. A MAC address is associated with the Data Link Layer. An IP
