Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think and learn like humans. The term can also be applied to any machine that exhibits traits associated with a human mind such as learning and problem-solving.

Types of Artificial Intelligence (AI)

1. Narrow or Weak AI: Designed and trained for a particular task. Virtual personal assistants, such as Apple’s Siri, Amazon’s Alexa, and Google Assistant, are examples of narrow AI.
2. General or Strong AI: A type of AI that can understand, learn, and apply its intelligence broadly, not just in specific instances. Currently, general AI exists only in theory.
3. Superintelligence: Significantly more intelligent than the best human minds. This type of AI does not yet exist and is a subject of ongoing debate and research.

Key Features of Artificial Intelligence (AI)

1. Machine Learning (ML): AI systems can learn from data and improve their performance over time.
2. Natural Language Processing (NLP): AI systems can understand and generate human language.
3. Computer Vision: AI systems can interpret and understand visual data from images and videos.
4. Robotics: AI systems can control and interact with physical devices.
5. Expert Systems: AI systems can mimic human decision-making abilities.
