Azure IoT's service that allows bi-directional communication between IoT applications and the devices it manages is called ________.
- Azure Data Factory
- Azure Functions
- Azure IoT Hub
- Azure IoT Suite
Azure IoT Hub is a service that facilitates bi-directional communication between IoT applications and the devices it manages. Azure Functions, Azure IoT Suite, and Azure Data Factory serve different purposes within the Azure ecosystem.
Which of the following was a precursor to the modern IoT?
- ARPANET
- Bluetooth
- ENIAC
- World Wide Web
ARPANET, the precursor to the modern internet, can be considered a precursor to the Internet of Things (IoT). ARPANET was one of the first wide-area packet-switching networks and laid the foundation for the interconnected networks that led to the development of IoT.
In which phase of the IoT project lifecycle is the scope and objectives of the project defined?
- Design
- Implementation
- Planning
- Testing
The scope and objectives of an IoT project are defined in the planning phase. During this phase, project goals, deliverables, and overall strategy are determined.
A manufacturing company is using IoT devices to monitor equipment health. They want to analyze this data and predict when a machine is likely to fail. This is an example of:
- Descriptive analytics
- Diagnostic analytics
- Predictive analytics
- Prescriptive analytics
Monitoring equipment health and predicting machine failures is a prime example of predictive analytics. Predictive analytics uses historical data and statistical algorithms to make predictions about future events, helping companies prevent costly machine failures.
One of the earliest implementations of IoT can be traced back to Carnegie Mellon University, where a ________ was developed.
- Internet-connected toaster
- Smart refrigerator
- Telemetry system
- Wireless sensor network
One of the earliest implementations of IoT can be traced back to Carnegie Mellon University, where a "wireless sensor network" was developed. Wireless sensor networks are a crucial component of IoT, as they enable the collection of data from various sensors and devices. These networks are a fundamental building block of IoT technology.
