ITIL 4 Foundation Practice Exam

The Internet of Things (IoT) is primarily characterized by the interconnection of devices that include embedded computing capability and network connectivity. This means that IoT encompasses a wide range of devices, such as sensors, home appliances, vehicles, and industrial machinery, all of which are equipped with the necessary technology to communicate with one another over a network.

This interconnectedness allows these devices to gather and exchange data, enabling automation and smart functionalities that were not possible before. For example, smart thermostats can learn user preferences and adjust heating or cooling automatically, thereby enhancing efficiency and user experience. The ability to connect, collect data, and provide insights distinguishes IoT from traditional IT, where devices may not have the same level of interactivity or'smart' features.

In contrast, the other options reflect narrower or inaccurate interpretations of IoT. The first choice limits the definition to traditional IT assets, ignoring the vast array of connected devices that are integral to IoT. The third choice suggests that devices can be interconnected without any computing capabilities, which contradicts the fundamental nature of IoT devices, as they require some computing power to process and transmit data. Lastly, restricting the interconnection only to mobile devices overlooks the myriad of other devices – such as home appliances
