Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think, learn, and solve problems autonomously. AI encompasses various technologies, including machine learning, natural language processing, and computer vision, allowing systems to analyze data, make decisions, and perform tasks typically requiring human intelligence. Its applications span industries from healthcare and finance to transportation and entertainment, continually evolving to enhance efficiency, accuracy, and innovation. AI's transformative impact is reshaping how businesses operate and how societies interact with technology, promising a future where intelligent machines collaborate with humans to tackle complex challenges and drive progress.
