Artificial Intelligence (AI) is the simulation of human intelligence by machines — enabling computers to perform tasks that would normally require human cognition: learning, reasoning, problem-solving, perception, and language understanding.

At its core, AI is a broad field of computer science concerned with building systems that can act intelligently in the world, whether that means recognising a face, recommending a movie, driving a car, or generating a poem.

Key Points

  • AI is the broadest umbrella — it encompasses Machine Learning and Deep Learning as subfields
  • Narrow AI (ANI): excels at one specific task (chess, image recognition, voice assistants)
  • General AI (AGI): hypothetical human-level intelligence across all tasks — does not yet exist
  • Super AI (ASI): hypothetical AI surpassing human intelligence in every domain
  • AI systems learn from data, rules, or a combination of both
  • Key AI capabilities: perception, reasoning, planning, natural language, learning, and action
AI TypeDescriptionExample
Narrow AI (ANI)Optimised for a single taskSiri, AlphaGo, spam filter
General AI (AGI)Human-level reasoning across domainsTheoretical — not achieved
Super AI (ASI)Surpasses human intelligenceTheoretical — science fiction

Real-World Example

Every time Netflix recommends a show, Google Maps reroutes you around traffic, or your email client moves spam to junk — that is narrow AI in action. Modern AI runs on billions of devices and affects nearly every industry.
