Artificial Intelligence (AI) is a transformative field of computer science that aims to create machines capable of performing tasks that typically require human intelligence. AI systems leverage algorithms, data, and advanced computing power to simulate human cognitive functions like learning, reasoning, problem-solving, and perception. These systems can range from simple rule-based programs to complex neural networks that excel in areas such as image recognition, natural language processing, and autonomous decision-making. AI has applications across various industries, including healthcare, finance, transportation, and entertainment, revolutionizing the way we live and work. As AI continues to advance, it holds the potential to address some of the most pressing challenges of our time while raising important ethical and societal questions.
