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 various subfields such as machine learning, where algorithms improve automatically through experience, natural language processing, which enables machines to understand and respond to human language, and robotics, where machines are designed to perform tasks in the physical world.

AI is utilized in diverse applications across sectors, including healthcare for diagnostic tools, finance for algorithmic trading, customer service through chatbots, and autonomous vehicles for navigation and decision-making. The aim of AI research and development is to create systems that can operate independently, adapting to new inputs and performing tasks that typically require human intelligence. As technology advances, AI is becoming increasingly integrated into everyday life, prompting discussions about ethics, job displacement, and the future of human-machine collaboration.
