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 and make decisions), and self-correction.

AI encompasses a variety of technologies and methodologies, including machine learning, where systems learn from data and improve their performance over time, and natural language processing, which enables machines to understand and generate human language.

AI can be categorized into two main types: narrow AI, which is designed for specific tasks such as facial recognition or internet searches, and general AI, which possesses capabilities comparable to human intelligence across a wide range of activities. Currently, most AI applications fall under the narrow AI category.

AI is increasingly integrated into various fields, such as healthcare, finance, transportation, and entertainment, enhancing efficiency, productivity, and the ability to analyze vast amounts of data. As technology advances, the potential applications and implications of AI continue to expand, prompting ongoing discussions about ethics, safety, and the societal impact of intelligent systems.
