PART - A
What is data collection in IoT?
Answer
Data collection in IoT refers to the process of gathering raw information from the physical environment using sensors, actuators, and connected devices. This data is captured, digitized, and transmitted over a network to a central system or cloud platform for storage, processing, and analysis. It serves as the foundation for IoT intelligence, enabling devices to monitor conditions, track assets, and trigger automated responses based on real-time environmental inputs.
Explain the difference between M2M and IoT.
Answer
The primary differences between M2M (Machine-to-Machine) and IoT (Internet of Things) are:
- Scope: M2M typically refers to point-to-point communication between two specific devices, whereas IoT is a broader ecosystem connecting various devices, sensors, and cloud services into a unified network.
- Connectivity: M2M often uses proprietary or point-to-point protocols (like cellular or wired), while IoT relies on standard IP-based internet protocols for global connectivity.
- Integration: IoT integrates data into enterprise applications and cloud analytics, whereas M2M is generally focused on isolated hardware-level interaction and monitoring.
