Artificial Intelligence (AI) is a branch of computer science aimed at building systems capable of performing tasks that typically require human intelligence. These tasks include learning, reasoning, problem-solving, understanding language, recognizing patterns, and making decisions. AI systems can range from simple rule-based programs to advanced machine learning models that improve over time with data.

AI is generally categorized into two types:

1. Narrow AI (Weak AI): Designed to carry out specific tasks, such as facial recognition, language translation, or providing recommendations. Narrow AI operates within predefined limits and lacks the broad cognitive abilities of humans.
2. General AI (Strong AI): A theoretical form of AI that would possess human-level intelligence and be capable of understanding, learning, and applying knowledge across a wide range of tasks. General AI does not yet exist but is a key area of research.

Not to be confused with Generative AI (GenAI), which refers to AI systems that create new content such as text, images, or music by learning from existing data patterns, General AI focuses on developing machines that can think, reason, and adapt like humans across different domains.
