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?
There would be too much interference going on. There would be no control of the airwaves that wireless networks adhere to. Since we are so focused on the technology that we cannot live without, it would be very frustrating and the technology would not work properly.
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?
You would need all of the above devices to make the network operate properly.
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.
Data Link, Physical, Application, Network, 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.
Lab 3.1Review 1. Why would a three- layer model of communication that has the layers physical, network, and application be insufficient to adequately describe network communication?
Because of the fact that you still need to describe how the data is packed and communicated through the communication.
2. What is the history of the OSI reference model? How did it come about and why was it created? Use…...

...Robin Woodruff NT1210 8/8/2014 Mrs. Oliver 1 Comparison between Microsoft and VMware With the Microsoft Cloud OS vision, people get one consistent platform that goes beyond just virtualization, and includes management, automation, development platform, network, data, and identity. Microsoft offers a platform that supports peoples’ needs from bare metal up through applications and out to devices, including mission-critical workloads, from leading solution providers that include Microsoft, Oracle and SAP. People can choose the platform that's right for their entire business, and adapt as the needs of their business change.​ In-text reference: (Microsoft, 2014). Microsoft changes Hyper-V in each version, which creates a learning curve for IT staff with every new Windows release. In-text reference: (IT World, 2014) VMware has publically changed its product roadmaps several times over the last few years. VMware touts these changes as product evolution, but existing people are left behind with a product that might be unsupported or unfit for the future. VMware's approach is to virtualize everything, and other components like apps, management, identity, and data are viewed through that lens only, without true consideration for the benefits provided by cloud services like application portability, resiliency, and elasticity as well as a common identity platform. Unlike Windows Server and Azure, VMware is not certified and supported by Oracle. In-text reference:......

Dedicated circuit – A electrical circuit created by a telco CO. on behalf of a customer, with circuits staying up all the time, dedicated for use by the customer that ordered the circuit, also known as leased lines, leased circuit and point to point. 3. Circuit switching - The overall process by which a series of Telco devices called circuit switches connect a circuit from one customer to another, with the device taking bits on one segment in the link and forwards those bits out the matching outgoing segment without storing the bits. 4. Leased line – A physical link between two locations provided by Telco, that allows two way communications between sites. Because the customer does not own the physical line between the sites, but rather pays a monthly fee for service called a leased line “AKA” dedicated circuit, leased circuit, and point-to-point. 5.

That would mean cable providers, cellphone providers, and internet providers would all have to use their own Wi-Fi frequencies. Without the WI-FI alliance it would be to hard to manage day to day life with all devices not being able to share hardware and software. Also there would be no real security so it would be easy for someone to hack all of your information. 3.1.2 A model that is used to visualize something that I would use is power points.
