CompTIA Network+ Practice Test

Which of the following describes IoT devices?

1. Devices that require manual operation only

2. Appliances that are connected to the internet

3. Standalone hardware with no connectivity

4. Devices that can perform complex computations

The correct answer is: Appliances that are connected to the internet

The choice that describes IoT devices accurately is the option that states they are appliances connected to the internet. IoT, or the Internet of Things, refers to a network of physical objects equipped with sensors, software, and other technologies that enable them to connect and exchange data with other devices over the internet. This connectivity allows IoT devices to be monitored and controlled remotely, leading to increased efficiency and convenience in various applications, such as smart homes, healthcare monitoring, and industrial automation. These devices span a wide variety of products, from smart thermostats and home security systems to wearables and connected vehicles. The other options lack alignment with the fundamental definition of IoT. Devices that require only manual operation do not utilize their connectivity features. Standalone hardware without any connectivity doesn’t fit the IoT model, as it does not benefit from the interconnectedness that characterizes IoT devices. Lastly, while some IoT devices can have advanced processing capabilities, not all IoT devices perform complex computations; many operate on simpler tasks and operate primarily through data collection and transmission.
