Which statement about IoT devices is correct?

IoT devices, or Internet of Things devices, are characterized by their ability to connect and interact with the internet and other devices. The correct statement highlights that IoT devices can encompass a wide array of objects, including common household appliances such as refrigerators and innovative gadgets like smart doorbells. This reflects the diverse nature of IoT technology where items traditionally not considered computers are now enhanced with internet connectivity and smart features, enabling them to communicate and share data.

In contrast, the other statements are not accurate representations of IoT devices. Many IoT devices are not limited to traditional computers and servers, as the term encompasses various everyday items. While some IoT devices may use wired connections, the majority rely on wireless connectivity to enable seamless communication in everyday settings. Additionally, while many IoT devices benefit from internet access to function optimally and facilitate data sharing, some can operate on local networks or within specific protocols without constant internet connectivity. Thus, the diversity and adaptability of IoT devices make them a significant component of modern technology.
