What is Artificial Intelligence?
Artificial Intelligence (AI) is technology that enables computers to perform tasks that normally require human-like abilities — such as recognising patterns, understanding language, making predictions, or solving complex problems.
Unlike ordinary programs that simply follow a fixed list of instructions written by a programmer, AI systems can adapt, learn from experience, and handle situations they haven't been explicitly programmed for.
Real-world analogy
Recognises patterns
AI can spot patterns in images, speech, and data that would take humans much longer to find — like identifying a tumour in an X-ray.
Understands language
AI can read, understand, and generate human language — powering chatbots, autocomplete, and voice assistants.
Makes predictions
AI systems predict future outcomes from past data — like what film you'll enjoy or whether an email is spam.
AI is not magic
AI cannot truly 'think' or 'feel'. It performs intelligent-seeming tasks by processing huge amounts of data.
Key vocabulary
- Algorithm — a set of steps a computer follows to solve a problem.
- Data — information collected from the real world (images, text, numbers, etc.).
- Pattern recognition — finding structure or regularities in data — a core AI ability.
- Model — an AI system that has been trained and can make decisions or predictions.
