How are IoT and WoT related?
The Internet of Things (IoT) is a network of devices that have embedded hardware and software to communicate and exchange data with other devices on the same network. It brings together various devices to work in collaboration, creating an intelligent network of things.
Web of Things (WoT) is related to IoT as it extends its capabilities by using web services to connect devices. While IoT allows interaction with different devices through the Internet, WoT provides a convenient single interface to connect all devices instead of requiring separate apps for each device. WoT enables all things to communicate with each other efficiently by integrating them together through the web, paving the way for smart homes, smart offices, and smart cities.
Explanation
The textbook establishes that IoT is the foundational network of connected devices, while WoT builds upon it by leveraging web services. The key relationship is that WoT solves the problem of needing multiple apps for different IoT devices by providing a unified web-based interface for communication. This makes WoT an enhancement or extension of IoT technology.
