Artificial Intelligence (AI) refers to the simulation of human intelligence processes by machines, particularly computer systems. These processes include learning (the acquisition of information and rules for using it), reasoning (the ability to solve problems through logical deduction), and self-correction. AI systems can be categorized into two main types: narrow AI, designed to perform specific tasks (such as voice recognition or language translation), and general AI, which aims to understand and reason about the world in a way comparable to a human being.

AI technologies encompass a wide range of subfields, including Machine Learning (where algorithms are used to analyze data and improve performance over time), natural language processing (enabling machines to understand and generate human language), computer vision (allowing machines to interpret visual information), and robotics (involving the design and use of robots).

The applications of AI are varied and extensive, including autonomous vehicles, virtual personal assistants, predictive analytics, and medical diagnosis systems. The ongoing development of AI raises important ethical and societal questions, particularly regarding job displacement, privacy, and decision-making transparency.
