In essence, a smart city collects real-time information from various sources (like sensors on streetlights, traffic cameras, or even people’s smartphones) and uses this data to make better, more informed decisions about how the city operates.

What is Artificial Intelligence (AI)? (Simplified for Beginners)

Think of AI as computer systems that can learn, reason, and solve problems in ways that traditionally required human intelligence. It’s not about robots taking over the world, but about making machines smarter and more helpful.

Here’s a breakdown of what AI can do:

• Learning: AI systems can analyze huge amounts of data to find patterns and make predictions. The more data they get, the smarter they become.
• Decision-Making: Based on what they’ve learned, AI can make choices or recommend actions.
• Understanding Language and Images: AI can process human language (like Siri or Alexa) and recognize objects or faces in pictures and videos.
• Automation: AI can automate repetitive tasks, freeing up humans for more complex work.

In a smart city, AI is the engine that transforms raw data into actionable insights, making the city "think" and adapt.

Why AI is the Brain of a Smart City
