Q.Which is not one of the features of IoT devices?

This is an MCQ asking you to identify which statement is not a feature of IoT devices.

IoT (Internet of Things) devices are embedded systems connected to the internet, designed to collect data, communicate with other devices, and often respond to commands. Their defining characteristics include:

• Remote controllability: IoT devices can be monitored and controlled from anywhere via the internet — a smart thermostat adjusted from your phone, a security camera accessed remotely, or industrial sensors managed from a central dashboard.
• Programmability: These devices run software that can be updated, configured, or reprogrammed to change behavior, add features, or fix bugs. A smart bulb's schedule can be reprogrammed; a fitness tracker receives firmware updates.
• Autonomous decision-making: Many IoT devices incorporate logic to act independently based on sensor input or predefined rules. A smart plug might cut power when it detects overheating; a connected irrigation system turns off when soil moisture is adequate.

The third option describes exactly this kind of autonomous behavior — the ability to make decisions (like shutting down) without human intervention when conditions warrant it. This is a standard feature in IoT systems for safety, efficiency, and reliability.

Since all three statements (a), (b), and (c) accurately describe IoT device features, none of them is "not a feature." Option (d) correctly recognizes this. …

The question asks you to identify which statement is not a feature of IoT (Internet of Things) devices. To answer this, you need to understand what capabilities define modern IoT systems.

IoT devices are built around three core principles: connectivity, intelligence, and autonomy. They connect to networks (often the internet) to send and receive data, they contain embedded processors that can execute logic, and they can make decisions without constant human intervention.

Remote controllability is fundamental. The entire point of IoT is that you can monitor and control devices from anywhere — adjusting your thermostat from your phone, turning off lights remotely, or checking security cameras while away. This is enabled by network connectivity and is a defining characteristic.

Programmability is equally essential. IoT devices run firmware and software that can be updated, configured with rules, and customized for different use cases. A smart sensor might be programmed to trigger alerts at certain thresholds; a smart appliance can follow schedules you define. Without programmability, these would be static, single-purpose devices. …
