Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think and act like humans. This encompasses a range of capabilities, including learning, reasoning, problem-solving, perception, understanding natural language, and decision-making. AI can be classified into two primary types: narrow AI, which is designed for specific tasks (such as facial recognition or language translation), and general AI, which aims to perform any intellectual task that a human can do.

AI systems utilize algorithms and large datasets to identify patterns and improve performance over time, making them adaptable and efficient in processing vast amounts of information. Machine Learning, a subset of AI, focuses on the development of algorithms that allow computers to learn from and make predictions or decisions based on data. Deep Learning, a further evolution, uses neural networks with many layers to analyze various factors in data, mimicking the neural structure of the human brain.

AI technology is widely used across various industries, including healthcare for diagnostics, finance for fraud detection, autonomous vehicles for navigation, and customer service through chatbots. As AI continues to evolve and integrate into daily life, it is reshaping how we work, interact, and make decisions, raising important ethical and societal questions about its impact.
