OSI shape - Assignment ExampleHowever, other similar system programs are non included in the scope of OSI model however they perceive an end users typing into a Layer 1 demand (Holmes, 2011 RingofSaturn, 2011). In other words, the screening mold kit and caboodle as an interface between users and network. Thus, it allows the users to access network operational assistances. In addition, this floor holds a multiplicity of required processes (Microsoft, 2011) 5 foundation LAYER 6 The presentation layer offers a range of encoding and encryption processes that are utilise to the data received from application layer. The purpose of these processes is to make sure that information received from the application layer of one system will be understandable to the application layer of another system. In addition, it works as a translator of the network since it translates the data to be accessible to the systems application layer. ... In this scenario, the complexity and size of a netw ork transport protocol completely depends upon the kind of service which is presented to it by the network layer. In addition, for a trustworthy network layer with virtual circuit potential, a negligible transport layer is necessary. On the other hand, if the network layer is untrustworthy and/or only facilitates datagram transitions method, the transport protocol should encompass widespread error discovery and recovery methods.Moreover, the transport layer is obligated for carrying out following tasks 8 NETWORK LAYER 9 Network layer offers freedom from data transfer technology and routing concerns, masks peculiarities of data transport medium from higher layers and offers switching and routing processes to create, uphold, and end network layer associates and transfer data among various users. In this scenario, the network layer is mainly responsible for domineering the processes of the subnet, and making a decision that which natural path the data should be based upon, main co ncerns of service, and other aspects. In addition, network layer of OSI model carries out following tasks (Fairhurst, 2001 Fairhurst, The Internetwork Protocol (IP), 2008 Microsoft, 2011) 9 DATA unify LAYER 10 The data link layer is the place where logical data and information (for representative network IP addresses) are actually interpreted into the electrical pulses that move over the physical layer. In addition, ATM, Frame Relay and DSL follow Data Link layer mechanisms. Additionally, the OSI model data link layer offers error-free communication of data frames from one node to another network node over the physical layer, permitting layers above it to suppose virtually error-free data and network
