Final answer:
IoT devices are advanced connected devices that interact with users, other devices, and software, offering high levels of intelligence and integration into daily life, acting akin to a personal digital companion or an extension of the user's senses. (option C)
Step-by-step explanation:
The difference between normal devices and IoT devices lies in their connectivity and level of intelligence. Normal devices typically function in isolation, performing specific tasks without the ability to communicate with other devices or systems. Connected devices, on the other hand, are capable of communication and interaction, but may only do so in a limited scope or predefined manner.
IoT devices, representing the Internet of Things, go much further by not only connecting and communicating between devices but also integrating with people, physical items, and software systems. This creates a powerful ecosystem where devices can learn from user interactions, make suggestions, and even automate processes without direct human intervention. The 'smart' in smart technologies implies an adaptive and responsive experience, where gadgets function almost as an extension of the user's senses or as a digital companion.
In this era of technophilia, users expect a seamless integration of technology into their daily lives. IoT devices become akin to an extra organ for sensation and communication, offering a level of convenience and personalization that was not possible with traditional devices.
