Artificial Intelligence (AI) refers to the development of computer systems that can perform tasks typically requiring human intelligence. These tasks include functions such as understanding natural language, recognizing patterns, reasoning, learning from experience, and making decisions. AI encompasses a wide range of technologies and methodologies, including Machine Learning, neural networks, Deep Learning, natural language processing, and computer vision.

Machine Learning, a subset of AI, involves algorithms that enable computers to learn from and make predictions based on data. Deep Learning, a further specialization, mimics the neural connections within the human brain to process complex patterns in large datasets. Natural language processing allows machines to understand, interpret, and respond to human language in a way that is both meaningful and contextually relevant.

AI applications are diverse and can be found in various fields, including healthcare, finance, transportation, and entertainment. They can enhance productivity, improve decision-making, and provide personalized experiences. As technology advances, AI continues to evolve, raising ethical considerations regarding privacy, bias, job displacement, and the potential for misuse, making it a significant focus of both research and discourse in contemporary society.
