Artificial Intelligence (AI) is a branch of computer science that focuses on creating intelligent machines that can think, learn, and act like humans. It uses advanced algorithms and machine learning techniques to enable computers to recognize patterns, make decisions, and solve problems. AI has the potential to revolutionize various industries, including healthcare, finance, transportation, and entertainment, by automating tasks, improving efficiency, and providing personalized experiences. However, there are also concerns about the ethical implications and potential risks associated with AI, such as job displacement, privacy, and bias.
