Artificial Intelligence (AI) is the branch of computer science that enables machines to think, learn, and perform tasks that typically require human intelligence. From recognizing speech and images to making decisions and predicting outcomes, AI is transforming the way we live, work, and interact with technology. By combining data, algorithms, and computing power, AI systems can analyze vast amounts of information, identify patterns, and improve their performance over time. Today, AI powers everything from virtual assistants and recommendation engines to autonomous vehicles and medical diagnostics, making it one of the most revolutionary technologies of our era.
