Artificial Intelligence (AI) is the simulation of human intelligence in machines designed to perform tasks that typically require human cognition. These tasks include learning, reasoning, problem-solving, perception, and natural language understanding. AI systems leverage algorithms, data, and computing power to analyze patterns, make predictions, and automate processes. Types of AI range from narrow AI, focused on specific tasks, to general AI, capable of human-like versatility. Applications span industries like healthcare, finance, transportation, and entertainment. Advancements in machine learning, neural networks, and robotics continue to revolutionize AI, enabling innovations like self-driving cars, virtual assistants, and personalized recommendations.
