What is artificial intelligence?

Artificial intelligence, or AI, is when a computer program is designed to do tasks that normally need human thinking — like recognizing a face, understanding speech, or recommending a film you might enjoy. AI is not magic: it learns by studying huge amounts of data and finding patterns, just like a student learns by studying lots of examples.

What Makes Something "AI"?

• It uses data — the program is trained on thousands or millions of examples.
• It finds patterns — the program learns what things have in common.
• It makes predictions or decisions — it applies those patterns to new situations.
• It can improve over time — the more data it sees, the better it gets.

AI Examples in Everyday Life

• A voice assistant (like Siri or Alexa) that understands spoken questions.
• A spam filter that learns to recognize unwanted emails.
• A recommendation system that suggests songs or videos based on what you have listened to.
• A photo app that recognizes faces or objects in pictures.
• A language translator that converts text between languages almost instantly.

Non-AI Examples

• A calculator — it follows fixed rules but does not learn or adapt.
• A light switch — it turns on and off, but it does not make decisions.
• A basic alarm clock — it rings at a set time but does not change its behavior.
• A digital thermostat with a fixed schedule — no learning, just a timer.
