解説
問 10
Incorrectア
Publishing one’s own profile to expand a circle of communication describes an SNS (Social Networking Service). Its target is communication between people, which differs from IoT, where physical objects are connected to the Internet.
Incorrectイ
Displaying advertisements for similar products when a certain product is searched for is recommendation (suggesting related products by analyzing browsing and search history) or behavioral targeting advertising, a marketing technique of e-commerce sites. It is not the connection and monitoring of sensor-equipped physical objects, so it is not IoT.
Incorrectウ
Recording classes or lectures in advance and distributing them over the Internet is an example of e-learning or video distribution (on-demand distribution). It is the distribution of content, which differs from IoT, where physical objects are connected to a network to collect and monitor their status.
- エ
正解 IoT (Internet of Things) is a mechanism in which physical objects equipped with sensors and communication functions are connected to the Internet, so that the objects’ status data can be collected and used for remote monitoring, control, and analysis. Choice エ remotely monitors, over the Internet, the operating status of power generation equipment, which is a physical object, and uses this for performance management, early detection of signs of malfunction, and repair response. Objects connect to a network and gather data to create value, which is exactly a typical example of IoT, so it is the correct answer.
ここがポイント
- IoT (Internet of Things) is a mechanism in which physical objects given sensors and communication functions are connected to the Internet, and their status data is collected and used for remote monitoring, control, and analysis.
- SNS (interaction between people), recommendation/targeting advertising (e-commerce marketing), and e-learning/video distribution (content distribution) all involve no connection of physical objects, which is the point that distinguishes them from IoT.
