Exercise 3.1.1 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? If each vendor had their own standards and protocols, we would have a harder time making devices that we use every day to inter-operate. We would to have multiple routers depending on the devices we own and probably would not be able to use internet when we’re in a café, library, or airport because of incompatibility.
Exercise 3.1.2 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? Laptop and Wireless router model is the easiest model to understand because we use them every day. HP Laptop Wireless ConnectionLinksys Wireless Router
Exercise 3.1.3 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? Consider direct connections between host devices and connections that require other routing equipment, such as a hub, switch, or router.
1. Data link 2. Physical 3. Application 4. Network 5. Transport
Exercise 3.1.4 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 a model is too granular ( too focused on individual detail)? If the data is too detailed, it may overlap with other information. However if the datais too general, then there may be crucial information missing
