What is Artificial Intelligence (AI)?
Definition
Artificial Intelligence (AI) is the simulation of human intelligence by machines, enabling them to perform tasks that typically require human cognition. These tasks include learning from experience, understanding natural language, recognizing patterns, solving problems, making decisions, and adapting to new situations.
Categories of AI
Narrow AI (Weak AI)
Designed for specific tasks like Siri, ChatGPT, or image recognition. Cannot generalize beyond its training.
General AI (Strong AI)
Hypothetical AI with human-like general intelligence. Does not exist yet.
Super AI
Theoretical AI surpassing human intelligence. Science fiction territory.
