Artificial intelligence (AI) refers to the simulation of human intelligence processes by computer systems. These processes include learning (the acquisition of information and rules for using it), reasoning (the ability to solve problems through logical deductions), and self-correction. AI is often categorized into two types: narrow or weak AI, which is designed to perform a specific task (like voice recognition or internet searches), and general or strong AI, which possesses the ability to understand, learn, and apply intelligence across a wide variety of tasks, much like a human.

AI encompasses various technologies, including machine learning (a subset of AI that uses statistical techniques to enable computers to learn from data), natural language processing (which allows machines to understand and respond to human language), and robotics (which involves the design of intelligent agents that can perform tasks in the real world). The development and integration of AI technologies have wide-ranging applications, from enhancing customer service with chatbots to advancing medical imaging and diagnostics, creating smart home devices, and powering autonomous vehicles. As AI continues to evolve, it raises important ethical considerations, such as issues of bias, privacy, and the future of work.
