2INTERNET OF THINGSAnswer 1:The StatementThe statement “the best interface for a system is no user interface” can be defined as asystem with no user interface implementation by which activities can be done in very few time orautomatically (Rayes & Salam, 2017). Or it can also be defined as elimination of the userinterface system from the whole process of a system in which any technology is being operated.This elimination can reduce many steps during execution of any system using technology whichwill help in completing the works in less time. With no user interface a user can complete his orher work by escaping several steps and can buy more time in completing that activity. Followingare the examples which can be helpful in making this definition clearer (Rayes & Samer, 2017).First Example: Nowadays automobile companies are implementing new and innovative technologies inthe cars in which one of the latest implications is the door opening system using mobileapplication. This implication has several steps due to the involvement of user interface system inthe whole system as the user will have to do several steps to open the locked door of the car;1.User will have to walk near the car2.Turn his/her phone on3.Search for the specific application4.After launching the application, gate will openWith no user interface system this could be done in two steps only:1.User reaches the car

User generally move to the café or the restaurantand orders the food or beverage then he or she has to again take phone out, search for theapplication, look into the application make payment procedures and then he can left out the caféor the restaurant. Again various steps can be reduced by “no user interface system”, by this userwill enter the café, orders whatever he wants and after eating or drinking he can leave thatrestaurant and the payment will be made automatically.
