解説
問 3
Incorrectア
This is merely a mechanism that links the auction venue and members' PCs over the internet, and the data is sent by PCs operated by people. It is not sensor-equipped objects connecting to the network, so this is an example of an internet auction (e-commerce), not IoT.
Incorrectイ
The form of moving groupware from an in-house server to an external data center so that it can be used anytime via the internet is an example of cloud computing (SaaS/ASP). It has no element of embedding sensors in objects, so it is not IoT.
- ウ
正解 IoT (Internet of Things) is a mechanism that connects physical objects embedded with sensors or communication functions to the internet, and collects and utilizes the data those objects generate. In choice ウ, a sensor is embedded in a physical object—the container of an oral medication—and a pharmacy obtains and manages the medication-taking history via the internet to support medication guidance. The essence of IoT is precisely that the object itself sends out data without human intervention, so ウ is the most appropriate example.
Incorrectエ
The mechanism of distributing lecture videos on a website so they can be taken on a smartphone or PC is an example of e-learning that uses video distribution. The viewing devices are existing information devices, and it is not sensor-equipped objects that send out data, so it is not IoT.
ここがポイント
- IoT is a mechanism that connects objects equipped with sensors or communication functions to the internet and collects and utilizes the data those objects generate.
- Cloud (use of external servers), e-commerce (online auctions), and e-learning (video distribution) are mechanisms in which people operate existing devices; distinguish them from IoT, in which the object itself sends out data.
