1. What is Artificial Intelligence (AI)? Artificial Intelligence (AI) is a branch of computer science that makes machines or computers think, learn, and act like humans . Example: Google Assistant answering questions Face recognition in mobile phones Chatbots replying to messages 2. Types of Artificial Intelligence AI is mainly divided into two types : A. Weak AI (Narrow AI) Weak AI is designed to perform one specific task only. It cannot think on its own. Examples: Google Assistant Siri Calculator Chess-playing computer 👉 Used in daily life 👉 Most common type of AI today B. Strong AI (General AI) Strong AI is an AI system that can think, learn, and make decisions like humans . Examples: Human-like robots (only in research, not fully developed) AI that can solve any problem like a human 👉 Still under development 👉 Does not exist fully yet 3. Applications of AI A. AI in Education AI helps students and teachers in learning and teaching. Examples: Online learning apps (Byju’s, Kha...
