Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think, learn, and problem-solve like humans. This technology encompasses a variety of subfields including Machine Learning, natural language processing, computer vision, and robotics. AI systems analyze vast amounts of data to identify patterns, make decisions, and improve over time through experience.

There are two main types of AI: narrow AI, which is designed for a specific task (such as virtual assistants like Siri or chatbots); and general AI, which aims to perform any intellectual task that a human being can do. While narrow AI is prevalent in applications today, general AI remains largely theoretical and is the subject of ongoing research.

AI technologies are increasingly used in various industries, enhancing efficiency and enabling complex decision-making processes, from healthcare diagnostics to autonomous vehicles and financial forecasting. As AI continues to evolve, it raises important ethical considerations regarding privacy, bias, and the potential impact on employment and societal structures.
