6. Internet of Things (IoT)

IoT connects everyday devices (like smart homes, cars, and wearables) to the internet.

These devices collect and share data to make life more convenient and efficient.
For example, smartwatches track health, while smart thermostats save energy.

7. Artificial Intelligence (AI) and Automation

AI allows systems to analyze data and make smart decisions automatically.

Examples:

  • Chatbots in customer support
  • Recommendation engines in e-commerce
  • Voice assistants like Alexa and Siri

AI and automation are transforming how ICT systems operate — making them faster and more intelligent.
