Artificial Intelligence (AI) refers to the simulation of human intelligence processes by machines, particularly computer systems. These processes include learning, reasoning, problem-solving, perception, language understanding, and decision-making. AI can be categorized into two main types: narrow AI, which is designed for specific tasks (such as facial recognition or internet searches), and general AI, which aims to perform any intellectual task that a human can do.

At the core of AI are algorithms and models that enable computers to analyze data, recognize patterns, and make predictions or decisions based on that information. AI technologies encompass various fields such as Machine Learning, Deep Learning, natural language processing, and robotics. The applications of AI are broad and influential, impacting industries like healthcare, finance, transportation, and entertainment by enhancing efficiency, accuracy, and the ability to handle large volumes of information. As AI continues to evolve, it raises important ethical considerations and challenges related to automation, data privacy, and the potential for bias in decision-making processes.
