The Internet of Things (IoT) refers to connecting any device with an on/off switch to the Internet. This includes devices like cell phones, appliances, wearables, and more. Connected devices allow things like monitoring medication reminders, efficient home heating, traffic management, and remote baby monitoring. The growth of IoT will impact industries like manufacturing, transportation, healthcare and more by increasing efficiency and reducing costs. India's IoT sector is being driven by the government, industries and startups working in areas like smart cities and healthcare. While IoT provides benefits like automation and savings, it also raises issues regarding privacy, security, compatibility and technology dependence.
