Internet of Things (IoT)

The Internet of Things refers to a network of physical objects embedded with sensors, software, and connectivity that enables them to collect, process, and exchange data autonomously.

• It acts as a foundational technological pillar for national initiatives such as the Smart Cities Mission, precision agriculture, and Industry 4.0 applications.
• It enhances public service delivery and resource efficiency through automated tracking in supply chains, smart power grid management, and remote healthcare monitoring.
• It introduces critical governance imperatives regarding data privacy, hardware supply-chain reliance, and cybersecurity vulnerabilities under India's evolving digital regulatory framework.

In General Studies Paper 3, UPSC frames questions on the Internet of Things by evaluating its practical applications in governance, agriculture, and infrastructure alongside its systemic security risks. Questions frequently ask candidates to analyze technological benefits against infrastructural bottlenecks, regulatory gaps, and data sovereignty concerns. Successful answers must provide balanced policy measures to deploy IoT solutions safely for inclusive socio-economic development.
