An IoT water level monitoring application requires updates from a sensor periodically,using the command/response paradigm. The application triggers a request every 1s. Theround-trip propagation delay between the application and the sensor is 12ms. On average,the sensor consumes 3ms to process each request. The application consumes 2ms to send orreceive any message. If the application blocks on every request to the sensor, how much ofits time budget can be saved by redesigning the application to use the publishcommunication model in the lieu of the command approach?...................................................7Q6.

Q1. What does the statement “the best interface for a system is no User interface”?When might this apply and provide examplesThe term No User Interface or Zero UI refers to the feature that enables users to have ascreen-less experience with their devices. According to (), it can be considered as a greatinterface design that can make a device more user friendly by which people can completetheir tasks more efficiently. Nowadays, people have become more app-obsessed and theyalways try to use best tools for their jobs. No one wants to go back to the age of flip-phone,everyone needs a smart phone to get immediate solution for their job-related problems(Kumar, Stecher & Tamura 2016, p.1870). For example: In this context, it can be stated that, the automobile engineers can use this zeroUI concept in solving the transportation problems. With the help of the technologicalprogress the engineers can make a touch-screen central control that helps the driver to look attheir way while driving. Another application of this screen-based thinking can be the app, bywhich people can get relief from swiping their smart phones (Al-Fuqaha, et. al., 2015). AsApple has launched a new app through which people can speak can speak to their screens forclicking a selfie or calling someone. This app may help the users to access the things moreeasily that they care about. Q2.Compare the bandwidth, distance, interference rating, cost and security of a)twisted pair cable, b. coaxial cable and c) fibre optic cable.
