About This Document

This paper is based on the internet of things, which will discuss the best interface for a system is no user interface. This paper will compare the bandwidth, distance, interference rating, cost and security of twisted pair, coaxial, and fibre optic cable. The paper will describe the issues associated with security and privacy on the internet of things context.

INTERNET OF THINGS2Q1) what does the statement "the best interface for a system is no User Interface"? When might this apply and provide two examples.This statement means that the interface complicates on the lives of individuals, rather than making them better. An example, lays out how we got to this app-obsessed point and how we could turn things and ensure that one is using the best tool for the job. This may or may not be anapp on your smartphone (Atzori, Iera & Morabito, 2010). Many companies as well as the designers are defaulting to using of the screens and the apps when they are actually making the task you are trying to achieve more difficult. Moreover, the statement could relate to the aspect that organization are fighting harder to keep the users in their ecosystem. This would be better onthe company shareholders, but not on the users experience (Gubbi, Buyya, Marusic & Palaniswami, 2013). The user experience should not be applicable to everything but rather an option on the table when individuals are solving problem. Individuals should focus more on something alluring other than the apps (Gubbi, Buyya, Marusic & Palaniswami, 2013). The attitude of there is an app for everything has ruined the design. It is important to embrace on the actual situation, and not just what works on the screen. It is important to stop designing the interface rather than solving the user problems. 2. Compare the bandwidth, distance, interference rating, cost and security of a) twisted pair cable, b) coaxial cable and 3) fibre optic cable.Twisted pair It is the lowest priced in addition to the most in-demand guided transmission medium. It comes with the two insulated copper wiring organized in the normal spiral patterns. The wire generally acts as the individual communication link. Over the longer ranges the cables could contain

When it comes to interferences the twisted cable are likely to reduce the cross talk between the adjacent pairs in the cable (Gubbi, Buyya, Marusic & Palaniswami, 2013). The neighbouring cable have bundle which have distinct twist sizes to decrease on the crosstalk inference. On the long distance links, the twist length varies from 5 to 15 cm and the thickness of the wire is from 0.4 to 0.9mm. The transmission of the signal are required about every 5 to 6 km. Twist cables are categorized as follows:Category 3: This is a UTP cable along with the connected linking hardware whose transmission features are particular up to 16MHz. Category four is the UTP cable and associated connecting hardware whose signal function up to 20 MHz The last is category five that is a cable and associated connecting hardware transmission around 100MHz (Kopetz, 2011).Figure 1: Shows the untwisted and twisted pair Coaxial cable It is similar to the twisted pair consisting of two conductors, but it is constructed differently in order to permit it to operate over wide range of the frequencies.
