The Internet of Everything

Cambridge National IT revision notes, key terms and practice questions.

What the Internet of Everything is

  • The Internet of Things (IoT) is everyday objects connected to the internet that collect and share data, such as smart thermostats and fitness trackers.
  • The Internet of Everything (IoE) goes further. It connects people, processes, data and things, so they can work together intelligently.

The four pillars

  • People: the users of connected devices and services.
  • Things: physical devices and sensors.
  • Data: collected by devices and turned into useful information.
  • Processes: the rules that get the right information to the right person or machine at the right time.

Uses

  • Smart homes: heating, lighting and security controlled by phone or voice. Smart cities: traffic lights that respond to traffic, and sensors that show free parking spaces.
  • Healthcare: wearable monitors that alert doctors. Transport: connected cars and live travel updates.
  • Agriculture: soil sensors that switch on watering when it is needed. Retail: stock tracked automatically.

Benefits and drawbacks

  • Benefits: saves time and energy, convenience, better decisions from real-time data, safety and health monitoring, and automation.
  • Drawbacks: security risks (every device could be hacked), privacy worries (lots of personal data), reliance on an internet connection, cost, devices that don't work together, and e-waste.
