【 The Internet ofthings (IoT) is the inter-networking ofphysical devices,vehicles ,buildings ,and other items embedded with electronics ,software,sensors,actuators,and network connectivity which enable these objects to collect and exchange data. In 2013 the Global Standards Initiative on Internet ofThings (IoT-GSI) defined the 10T as " a global infrastructure for the information society, enabling advanced services by interconnecting (physical and virtual) things based on existing and evolving interoperable information and communication technologies" and for these purposes a "thing" is "an object ofthe physical world (physical things) or the information world (virtual things). which is capable ofbeing identified and integrated into communication networks". The 10T allows objects to be sensed or controlled remotely across existing network infrastructure ,creating opportunities for more direct integration of the physical world into computer - based systems,and resulting in improved efficiency. Accuracy and economic benefit in addition to reduced human intervention. When IoT is augmented with sensors and actuators,the technology becomes an instance of the more general class of cyber­ physical systems,which also encompasses technologies such as smart grids,virtual power plants ,smart homes ,intelligent transportation and smart cities. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Intemet infrastructure. Experts estimate that the 10T wi l1 consist of about 30 bi l1ion objects by 2020. 】 Based on the paragraph above,we know that the applications ofthe 10T include (98) . RFID technology makes it possible to automatically (99) every object on the Internet ofthings,and is the foundation ofnetworking. From the industry point of view,IoT is mainly involved in industries including (100). A. environmental monitoring B.intelligent transportation C.energy management D.all ofthe above A. identify B.find C. track D. encrypt A. electronics B.communication C. software D. all of the above
