What is the Exclusive Pair communication model in WebSocket APIs?
Exclusive Pair is a bidirectional, fully duplex communication model that uses a persistent connection between the client and server.
What are the components of an IoT system?
An IoT system comprises of devices, resources, and controller services.
Explain the role of resources in an IoT system.
Resources are software components on the IoT device used for accessing, processing, and storing sensor information, or controlling connected actuators.
What is the function of a Controller Service in an IoT system?
Controller service is a native service that runs on the device and interacts with web services to send data from the device and receive commands for device control.
How does the Exclusive Pair communication model enable communication in WebSocket APIs?
It allows bidirectional communication between the client and server by establishing a persistent connection.
What are the core principles of REST architecture?
Representational State Transfer (REST) architecture focuses on stateless communication, uniform interfaces, and client-server separation.
What are the two ways in which a Web Service can be implemented according to the text?
HTTP and REST principles (REST service) or using WebSocket protocol (WebSocket service)
What is the main responsibility of the Analysis Component in an IoT system?
Analyzing the IoT data and generating results in a user-friendly form.
Describe the functionality of an IoT Application.
Providing an interface for users to control and monitor the IoT system, view system status, and access processed data.
What is the key characteristic of a Level-1 IoT system?
A single node/device that performs sensing, actuation, data storage, analysis, and hosts the application.
In which scenarios are Level-1 IoT systems most suitable?
For low-cost, low-complexity solutions with small data volumes and non-intensive analysis requirements.
What is the main difference between Level-1 and Level-2 IoT systems?
Level-1 systems perform local analysis, while Level-2 systems have a single node for sensing, actuation, and local analysis.
What are the four main capabilities that an IoT system provides?
Identification, sensing, actuation, communication, and management
List four types of IoT protocols used at different layers.
802.3, 802.11, IPv4, HTTP
Explain the concept of REST architecture principles in relation to IoT.
REST architecture principles emphasize stateless communication, uniform interfaces, and client-server interactions in IoT systems.
What is the purpose of WebSocket-based communication APIs in IoT?
WebSocket APIs facilitate full-duplex, real-time communication between IoT devices and servers.
Describe the Exclusive Pair communication model in IoT.
The Exclusive Pair model involves two devices communicating exclusively with each other without interference.
What are some key components of an IoT device?
I/O interfaces for sensors, Internet connectivity interfaces, memory and storage interfaces, audio/video interfaces
Test your knowledge on IoT levels, deployment templates, database storage options, web services, and analysis components as outlined in the book by Bahga & Madisetti. Explore concepts like local and cloud databases, REST services, WebSocket protocols, and data analysis in IoT applications.
