Imagine you are a wireless network contractor and you are meeting with a potential client over lunch to discuss the possibility of setting up a wireless network in the client's building. She mentions that she has heard of the OSI model but does not fully understand it and asks you to explain it to her. She has limited technical background. How would you describe the OSI model to somebody like this potential client who does not have a technical background? Come up with an analogy, that will help clarify your explanation. Note: If you decide to use an analogy it should be original and not based on the example provided.
