Artificial intelligence (AI) refers to the field of computer science focused on creating systems or machines that can perform tasks typically requiring human intelligence. These tasks include learning from experience (machine learning), understanding natural language, recognizing patterns, solving problems, and making decisions. AI encompasses various subfields, such as machine learning, where algorithms analyze data and improve their performance over time; natural language processing, which enables machines to comprehend and generate human language; and computer vision, which allows systems to interpret and understand visual information from the world around them.

AI technologies can be classified into two main categories: narrow AI, which is designed for specific tasks (like voice assistants or recommendation systems), and general AI, which aspires to perform any intellectual task that a human can do. While narrow AI is widely implemented across various industries today, general AI remains largely theoretical and a subject of ongoing research. The impact of AI on society is profound, driving advancements in numerous sectors, including healthcare, finance, transportation, and entertainment, and raises important ethical considerations regarding automation, privacy, and decision-making.
