Question

2.1 Describe the five principles that were followed/applied to arrive at the seven osi layers.

Answer 1

1.The layer boundaries should be chosen to minimize the information flow across the interfaces.

2.Each layer should perform a well-defined function.

3.A layer should be created where a different abstraction is needed.

4.The function of each layer should be chosen with an eye toward defining internationally standardized protocols.

5.The number of layers should be large enough that distinct functions need not be thrown together in the same layer out of necessity and small enough that architecture does not become unwieldy.
