Artificial intelligence (AI) can be defined as a machine's ability to mimic human intelligence through behaviors like learning and problem solving. AI is demonstrated through technologies like robots, autonomous vehicles, digital assistants, and machine learning systems. While AI systems can be programmed to perform tasks, they currently lack the ability to think independently or have social interactions like humans. As AI continues to advance, it will become more integrated into everyday life, so it is important to understand both its capabilities and limitations.
