The Internet of Things refers to a network of devices that:

1. An ordinary computer network links laptops, desktops, servers, tablets and phones. 2. The Internet of Things widens that idea to everyday appliances such as bulbs, fans and refrigerators. 3. It is a network of devices that have embedded hardware and software to communicate with other devices on the same network. 4. Communicating here means both connecting and exchanging data. 5. The devices can also be reached from computers or smartphones, so option B is wrong. _Source: syllabus Informatics Practices Class 11, Ch 2 'Emerging Trends', S2.4 Internet of Things (IoT)_
