What do the Open Systems Interconnection (OSI) and the Transmission Control Protocol/Internet Protocol (TCP/IP) models have in common?

What will be an ideal response?

First, they are both open architecture models. This means that anyone, anywhere, at any time, can freely design or create technologies based on these models, which is a real advantage. Second, both models are based on a layered architecture. This means that each model can be broken into several distinct components, called layers. Each layer within the model has its own particular and specific responsibilities and functionalities. A major topic discussed throughout this text is what these layers do, how they do it, and why. And finally, each model is well established and accepted by the data and telecommunications industries as models that provide clear guidelines as to how to build a data communications network that works. But remember, models are conceptual guidelines; how they are physically implemented can vary.
