Artificial Intelligence (AI) refers to the capability of a machine or computer system to perform tasks that typically require human intelligence. This includes a range of activities such as learning, reasoning, problem-solving, perception, language understanding, and even decision-making. AI systems are designed to mimic human cognitive functions, and they can be categorized into two main types: narrow or weak AI, which is designed for specific tasks, and general or strong AI, which would have the ability to understand, learn, and apply intelligence across a wide range of tasks similar to human intelligence. AI technologies encompass machine learning, natural language processing, computer vision, robotics, and other disciplines, contributing to the development of systems that can autonomously perform complex tasks.
