OSI, TCP/IP models comparison

entanglements rely on communications protocol to operate efficiently. Protocol is ?an retain upon format for directting data amidst twain devices? (Webopedia, 2008). Network protocol design is explained by two moldings, The OSI model and the transmission trim protocol/IP model. The OSI model was developed by the internationalist plaque for Standardization in an attempt to provide standards for how benefit should work. The model is theoretic in nature, and is divided into seven divers(prenominal) tiers. Each of these beds defines authoritative features and functions of a network. It could be difficult to insure the difference between severally layer, because some network systems do not entirely follow the model. Still, the OSI model is considered to be ?the model? to base all in all network protocols. The 7 layers of the OSI model are, in ascending order, the carnal layer, the data touch layer, the network layer, the transport layer, the session layer, the unve iling layer, and the application layer. at a time we will talk about what each of these layers is responsible for. ?The personal layer is the physical point of connection between a computer and the network. This layer controls the transmission of information, speckle specifying the mechanical and galvanic characteristics of the protocol in terms of association size, pin assignments, and voltage levels? (Raja, Nwankwo, & Martha, n.d.).

?The data link layer is primarily touch on with the packing and unpacking of data packets so that they green goddess be encoded and decoded into bits that lead them to be se nt through the network. This layer supports ! error treatment in the physical layer. Also, this layer is sometimes divided into two sub-layers called the media access control ( mac) and logical link control (LLC). The MAC controls flow of data across the network and gives permission to transmit data. The LLC controls frame synchronization and flow control?
