Compare and contrast tcp ip and osi

Compare and contrast tcp ip and osi

OSI model has a separate Presentation layer and Session layer. Network layer of OSI model provides both connection oriented and connectionless service.

It is a robust and flexible model. Whereas, OSI is a conceptual model.

difference between osi and tcp ip model tutorialspoint

Hosts use a discovery protocol to obtain the identification of gateways and other hosts attached to the same network subnetwork. Protocols are hidden in OSI model and are easily replaced as the technology changes.

It translates the network logical address into physical MAC address so that the two systems residing in the different networks could also communicate efficiently.

why tcp ip is used instead of osi

It performs tasks such as translation, encryption and compression where the actual information existing in the form of character strings, numbers, symbols is encoded into bit streams, converted into another form and compressed. Since these two layers deal with functions that are so inherently specific to each individual networking technology, the layering principle of grouping them together related functions is largely irrelevant.

Similarities between osi and tcp/ip model

Internet X. It has 7 layers The transport layer handles all error detection and recovery. Hosts use a discovery protocol to obtain the identification of gateways and other hosts attached to the same network subnetwork. The transport layer of the OSI model checks source-to-destination reliability. Both are reference models. Network Layer is both Connection Oriented and Connection less. Internet The protocols came first, and the model was really just a description of the existing protocols. OSI model defines services, interfaces and protocols very clearly and makes clear distinction between them. It is robust and flexible, but not tangible. The down side of this ordering is that the designers did not have much experience with the subject and did not have a good idea of which functionality to put in which layer. Related Differences:. De-facto OSI Standard legislated by official recognized body.

The transport layer of the OSI model checks source-to-destination reliability. Over the years it has handled most challenges by growing to meet the needs.
