Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think and act like humans. It encompasses a wide range of technologies and approaches, including machine learning, natural language processing, computer vision, and robotics, among others.

AI systems are designed to perform tasks that typically require human intelligence, such as visual perception, speech recognition, decision-making, and language translation. These systems learn from data, allowing them to improve their performance over time without being explicitly programmed for every task.

AI has applications in various industries, including healthcare, finance, transportation, and entertainment, and has the potential to significantly impact how we live, work, and interact with technology in the future.
