Artificial intelligence (AI) refers to the simulation of human intelligence in machines designed to think and act like humans. These systems can perform tasks such as learning, reasoning, and problem-solving, often using data to improve their performance over time. AI is increasingly integrated into various applications, from virtual assistants like Siri to advanced robotics. The field of AI encompasses various techniques, including machine learning and deep learning, which enable computers to learn from experience. As AI continues to evolve, it holds the potential to revolutionize industries, enhance productivity, and improve decision-making processes across the globe.
