Assessment item 2

Task

Provide short answers to the following questions.  The answers should be limited to between 0.5 and 1 page. Follow the presentation instructions and marking criteria below.

Q1) What does the statement "the best interface for a system is no User Interface"?  When might this
apply and provide two examples.

Q2) Compare the bandwidth, distance, interference rating, cost and security of a) twisted pair cable, b) coaxial cable and 3) fibre optic cable.  Use current data, give specific details for at least 3 types of cable within each category, these should have different specifications, rather than simply different brands of the same type.

Q3) The three common ways to obtain information from IoT devices are sensors, RFID and Video tracking.  Compare the three technologies by addressing the advantages, disadvantages, key requirements for the things.  Provide two applications of each (these applications should NOT be sourced from the textbook).  You may use a table to present the material if you wish.

Q4) Discuss the issues associated with security and privacy in the context of the Internet of Things.

Q5) An IoT water level monitoring application requires updates from a sensor periodically, using the command/response paradigm. The application triggers a request every 1 s. The round-trip propagation delay between the application and the sensor is 12 ms. On average the sensor consumes 3 ms to process each request. The application consumes 2 ms to send or receive any message. If the application blocks on every request to the sensor, how much of its time budget can be saved by redesigning the application to use the publish/subscribe communication model in lieu of the command/response approach?

Q6) Describe Nielson's Law.  How does it relate to Moore's Law?  What are the implications for the
Internet of Thing?
