AI stands for Artificial Intelligence. It refers to the development of computer systems that can perform tasks that typically require human intelligence. AI systems are designed to perceive their environment, reason, learn from experience, and make decisions or take actions to achieve specific goals. AI can be categorized into two types: Narrow AI and General AI. Narrow AI is designed to perform specific tasks, such as speech recognition or image classification, while General AI aims to possess the ability to understand, learn, and apply knowledge across various domains, similar to human intelligence.
