Lab 3.1

Exercise 3.1.1 – 3.1.5

What would happen if wireless devices were not governed by the Wi-Fi Alliance and each vendor had its own standards and protocols? What impact would this have on your personal life or business communications?

The consumer would have to buy accessories for each personal branded device they have for example if you had a Mac and a PC you would need a separate router for each device because the manufacturers would require you to use their own brand for each. It would be very hard for mobile devices to connect at coffee shops or café’s because of compatibility issues so there would be a setback in communications economically, thus slowing down many aspects of the daily business life.

Give another example of a model that is used to visualize something that is difficult to observe or perceive? How does the model make it easier to understand?

The OSI model is a good example because it the process and the direction of the process.

Based on what you already know about networks, what are the different layers you think would be necessary for communication to be mapped to a model?

Physical Data, Link, Network, Transport, session, and presentation.

The granularity of the reference model will often determine the usefulness of the model. What will happen if a model is too general? What will happen if it is too granular?

If the model of the reference is too general it will be very vague and there would be a lack of information for the user to come to any conclusions. If the model is too granular there would be so much information quite possibly too much information for the user to process.
