Artificial intelligence (AI) is the field of computer science focused on creating machines that can perform tasks typically requiring human intelligence, such as learning, problem-solving, perception, reasoning, and decision-making. It achieves this through advanced techniques, including machine learning and deep learning, which enable systems to learn from vast amounts of data, recognize patterns, and adapt to new inputs. AI powers a wide range of applications, from digital assistants and chatbots to self-driving cars and smart home devices.
