Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think and learn. These systems can perform tasks such as problem-solving, understanding natural language, and recognizing patterns. AI is used in various applications, including virtual assistants, recommendation systems, and autonomous vehicles. AI can be categorized into two main types: narrow AI and general AI. Narrow AI is designed for specific tasks, like image recognition or language translation, while general AI aims to understand and reason across a wide range of subjects, similar to human intelligence. Currently, most AI systems are narrow AI.
