Artificial Intelligence (AI) refers to the simulation of human intelligence processes by machines, particularly computer systems. These processes include learning, reasoning, problem-solving, perception, language understanding, and decision-making. AI systems can be classified into two main categories: narrow AI, which is designed for specific tasks (such as language translation or facial recognition), and general AI, which aims to perform any intellectual task that a human can do.

AI employs various techniques, including Machine Learning, where algorithms learn from data to improve performance over time; Deep Learning, which uses neural networks to analyze complex patterns; and natural language processing, enabling machines to understand and generate human language. AI applications span numerous fields, including healthcare, finance, transportation, and entertainment, transforming how we interact with technology and driving innovation across industries.
