Artificial intelligence (AI) refers to the simulation of human intelligence processes by computer systems. These processes include learning, reasoning, problem-solving, perception, and language understanding. AI can be broadly categorized into two types: narrow AI, which is designed to perform specific tasks (such as voice recognition or playing chess), and general AI, which aims to possess the ability to perform any intellectual task that a human can do. AI systems utilize algorithms and computational models to process and analyze large sets of data, allowing them to improve their performance over time through experience, often termed as machine learning. The applications of AI span various fields, including healthcare, finance, transportation, and entertainment, and its development raises important ethical and societal considerations as it becomes increasingly integrated into everyday life.
