The correct answer is

A network of connected devices sharing data

The term "Internet of Things" (IoT) refers to a network of interconnected devices communicating with each other and exchanging data through the internet. Let’s explore this concept further to confirm why "A network of connected devices sharing data" is the correct description.

  1. Definition: The Internet of Things is an ecosystem where various devices such as sensors, appliances, and other equipment are interlinked to collect and share data automatically. These devices can range from simple household items to sophisticated industrial tools.
  2. Features of IoT:
    • Connectivity: Devices are connected through the internet, allowing them to communicate with each other.
    • Smart Technology: IoT employs smart sensors and software to process and analyze data, often in real-time.
    • Automation and Control: IoT enables automation by interfacing various devices to perform tasks without human intervention.
  3. Ruling Out Other Options:
    • A type of programming language: IoT is not a programming language. Programming languages like Python or Java may be used to create IoT applications, but they are not IoT themselves.
    • A single device connected to the internet: While individual devices can connect to the internet, IoT specifically refers to a network of multiple devices interacting with each other.
    • Only computers communicating online: IoT extends beyond computers to include various types of devices. Therefore, it is not limited to computers communicating online.
  4. Conclusion: Based on the definition and characteristics of the Internet of Things, "A network of connected devices sharing data" is the most comprehensive and accurate description of IoT.
