In the OSI reference model, the communications between a computing system are split into seven different abstraction layers. What are these layers? (1 Mark) On the appropriate rows, write a brief description summarising the function of each layer and a corresponding example of a protocol used in that layer. (3 Marks) Also briefly answer, why is there a need for a standard model like OSI in networking? (1 Mark) (5 Marks)
