INTERNET OF THINGS2Q1“The best interface for a system is no User Interface” has been used categorically toimply that, what application Interface refers to as best may not be the best interface when itcomes to systems user application interface. Users of the system are quite different from machineand requires to have very attractive and accommodating interface (Krishna, 2015). Requirementsof User Interface should be met according to users need such as navigation and easy to operate.With no User Interface, what is left is for machine to help human being do the business activitiesinstead of Users adopting the need to operate applications. It is applicable in cases wheremachine is self-directing on what should be done instead of users interacting with it. Theexamples on this case are; eliminating UI that car owners use to open their cars and applicationsthat users use to order online.Q2Twisted pair cable has the following specifications on bandwidth; CAT 4=20 MHZ, CAT5=100MHZ and CAT 6= 250MHZ. The maximum length of performance that twisted cable cantake is 100M. The interference rate of CAT 4 = 20Mbps, CAT 5= 100Mbps (2 pair) and CAT 6=10,000Mbps. The bulk price of UTP cable 5 pairs which double shielded and AWG stranded is$237.62 in a ready market. On security matters, UPT does not permit crosstalk between wiresand is prone to radio frequency. Coaxial cable bandwidth are; Wireless G (802.11g) = 54Mbps,WAN-10 Base-T= 10Mbps and cable broadband= 52Mbps (KOEGEL, YU, & LUA, 2009). Themaximum distance of a coaxial cable is 380M. The interference rate of a coaxial cable increaseswith length. The cost is dependent on the type of cable. RG6 which is of Standard Shield typeranges from $50-$200 for 30,000 miles. It is believed to be more secure than twisted cable. Thebandwidth of a fibre optic cable is 1Gbps, its operating distance is between 850nm and 1300 nm.

In security terms, it is thebest in data protection.Q3CategorySensorsRFIDVideo TrackingAdvantagesHelp in solving securityproblemwhileprotecting valuablesControl activities byproviding accurate data(Meyer, Ruppen &Magerkurth, 2013)It can store moreinformation thanbarcodeVersatile innatureAble to read andwrite, unlikebarcodeIncreasessecurity in storesHelps inpreventingshopliftingIt providesefficientmanagement bysurveillanceDisadvantagesEasily manipulatedBreak downCostly due touse of batteriesRemote readingis interferedwithbyelectromagneticIt requiresexpert to fix andanalyzeRequirementsRangeBandwidthaccuracyresolutionTags productionSoftwareBlank RFIDCamerasComputerDSP boardApplicationCash pointsInventorySupermarkets
