Artificial intelligence (AI) refers to the simulation of human intelligence processes by machines, particularly computer systems. These processes include learning (the acquisition of information and rules for using it), reasoning (using rules to reach approximate or definite conclusions), and self-correction. AI incorporates a range of technologies, including machine learning, natural language processing, and robotics, allowing systems to perform tasks that typically require human intelligence, such as understanding language, recognizing patterns, solving problems, and making decisions. AI can be classified into two main types: narrow AI, which is designed for specific tasks (like voice assistants or recommendation systems), and general AI, which possesses the ability to understand or learn any intellectual task that a human being can do. The field of AI is rapidly evolving, with applications across numerous industries ranging from healthcare to finance, emphasizing its growing impact on society and the economy.
