Artificial intelligence (AI) is the broad field of computer science concerned with creating intelligent machines that can reason, learn, and act autonomously. AI excels at processing massive amounts of data and identifying patterns humans might miss.

Expert systems are a specific type of AI application designed to emulate the decision-making ability of a human expert in a particular domain. They are essentially software programs that capture and reason through knowledge from a specific field, acting as a consultant for users.

Here's how AI and expert systems connect:

• AI as the Foundation: Expert systems rely on AI techniques like reasoning and knowledge representation to function.

• Expert Systems in Action: These systems put AI to practical use by applying knowledge from a specific area to solve problems or offer guidance. Imagine a medical diagnosis tool that uses AI to analyze patient data and suggest potential illnesses based on an expert doctor's knowledge.

Overall, AI provides the underlying intelligence, while expert systems are a way to harness that intelligence for practical applications in specific domains.
