Comparison between OSI and TCP model In this task I will produce the similarities and differences between the OSI model and TCP model. Similarities Both models are constructed with layers These models share Application Layer they have comparable transport and network layers Both model assume that individual packet may take different paths but will end up in the same destination They both provide a oriented end-to-end transport service Both are based on a stack of independent protocols

Differences OSI model has 7 layers TCP model has 4 layers TCP is simple model since it has few layers TCP supports internetworking but OSI doesnt support internet working The functions of each layer are in each model If error detected in packet then TCP model will be retransmitted OSI model supports both connectionless and connection-oriented communication in the network layerConclusion Overall my conclusion about OSI model is that the each layer has different data type handled. OSI model reduces complexity, has standardizes interface, and can be improved when technology improves. This layer is not a simple layer since it has 7 layers so the model is more complicate then the TCP model. Each layer has its own characteristics, functions and features. The OSI model shows the communication between two different hosts. The TCP model exchanges the data between two hosts. This model is designed to send packet data overt internet. TCP is a transport layer in the OSI layer - it is used to create a connection between remote computers by transporting and ensuring the delivery of messages over networks and the Internet. This protocol operates the transport layer.
