2INTERNET OF THINGSQuestion 1What does the statement the best interface for a system is no User Interface? When might thisapply and provide two examples.SolutionA divided borderline, across which two or more different elements of computer system,interchange various information is known as an interface. The interchange can bewithin,computer hardware,humans, peripheraldevices, softwareand amalgamation of these.Some hardware devices of a computer, for example atouch screen, can both send and receiveinformation via this interface. However, other devices, for example a microphone or a mouse canonly allocate an interface to send information to a particular system. Theuser interfaceor UI isthe space where intercommunication between the computer systems and the users occur (Pfaff,2012). The objective of this communication is to enable perfect management and operation ofthe system from the side of the user, whereas the system gives a feedback data at the same timethat supports thedecision making process of the operator. Examples of user interfaces are thehandtools,communicative features of operating systems of computers, processcontrols andheavy machineryoperator controls.Seizing of no user interface has been the case in the modern world where users considerthe computer systems with the best interface are those that uses no user interface. The statementmentioned above has been promoted in that voice user interface or VUIs is the best as the systeminterface compared to the graphical user interface or GUI (Johnson, 2013). Communicating witheach other is absolutely different from the way interaction is done with the graphical interfaces.
