3. How do expert systems decide what to do?They have a knowledge base of facts and if‑then rules, and an inference engine that applies those rules to data, using forward or backward chaining to reach a conclusion.
4. Why were expert systems important in the 1980s?They were among the first AI programs to help people in real jobs, like diagnosing diseases or finding minerals, and showed that computers could be useful helpers.

Artificial Intelligence (AI): The simulation of human intelligence in machines, enabling them to perform tasks that typically require human cognitive abilities.
Knowledge Base: A structured repository containing domain-specific facts, heuristics, and rules essential for an expert system's operation.
Inference Engine: The control mechanism of an expert system that applies logical rules to the knowledge base to derive conclusions or solutions.
Symbolic Reasoning: A form of AI reasoning that manipulates symbols representing concepts and relationships, rather than numerical data.
