Artificial Intelligence (AI) refers to the capability of a machine or computer to simulate intelligent behavior that typically requires human-like cognitive functions. This includes learning, reasoning, problem-solving, perception, language understanding, and even decision-making. AI systems are designed to analyze data, recognize patterns, and make decisions based on the information they process.

AI can be categorized into two main types: narrow AI and general AI. Narrow AI, also known as weak AI, is designed for specific tasks, such as image recognition, natural language processing, or playing games. These systems perform exceptionally well in their designated areas but lack general intelligence. In contrast, general AI refers to a theoretical form of AI that would possess the ability to understand, learn, and apply knowledge across a broad range of tasks, similar to a human being, though this remains largely speculative at present.

AI technologies use various algorithms and models, including Machine Learning, Deep Learning, and neural networks, to improve their performance as they process larger datasets over time. As AI continues to evolve, it plays an increasingly significant role in diverse fields such as healthcare, finance, transportation, and entertainment, driving efficiency and opening up new capabilities and innovations.
