AI refers to the branch of computer science that focuses on creating machines or software capable of performing tasks that typically require human intelligence. This includes processes like learning (via algorithms), reasoning, problem-solving, understanding natural language, and perception.

AI is a system or program designed to mimic human decision-making and behavior. It achieves this by analyzing data, identifying patterns, and making predictions or decisions based on the information provided. Examples include self-driving cars, virtual assistants, and recommendation systems.

AI represents an attempt to understand and replicate intelligent behavior. It involves studying how humans think and act and using this understanding to create algorithms and systems that can simulate these behaviors, aiming to develop machines that can "think" or "learn" like humans.
