Display one image and 5 points of comparison between OSI and TCP/IP.


1. 7 layers present in the architecture.
Only 4 layers are present.
2. Not practically implemented yet.
Practical Model.
3. Layering aspects, functions of each layer and division of responsibilities are specifically presented by this model.
Division of responsibilities on each layer is not so specific.
4. The concept of services, interfaces and protocols are well explained.
No clear distinction between the three
5. Model was devised first and protocols were latter fitted to appropriate layers.
The protocols came first and model was just explanation of protocols based on 4 layers.
6. Widely used as a standard reference model in the design of computer networks.
Not considered as a design standard due to the failure in distinguishing services, interfaces and protocols.
7. Connectionless and connection oriented services are there in Network layer but only connection oriented services in Transport layer.
Connectionless and connection oriented services in transport layer but only connectionless service in Network layer.
8. This is a protocol independent model.
This is a protocol specific model.
