What is the importance of the OSI model?
January 31, 2010 5:29AM
The OSI model is a theoretical model of how protocols and standards should work together for a common understanding of network communications. It describes what happens when one packet goes from one device to another. Without the model we would not have an understanding of how to connect networks together.
A network engineer needs a very good understanding of the model and the responsibilities of each layer of the model.
