Which of the following is NOT a component of a Knowledge Based System?

1. K-Map

2. Inference Engine

3. User Interface

4. Knowledge Based

The correct answer is: K-Map

In a Knowledge Based System, the key components typically include the Knowledge Base, Inference Engine, and User Interface. The Knowledge Base contains the domain knowledge, facts, and rules; the Inference Engine applies logical rules to the knowledge base to derive conclusions or make decisions; and the User Interface facilitates interaction between the user and the system. A K-Map, or Karnaugh Map, is a tool used in simplifying Boolean algebra expressions primarily in digital logic design and not a primary component of Knowledge Based Systems. It is not typically associated with the construction or functioning of these systems, which focus on reasoning and decision-making based on stored knowledge. Therefore, the correct choice identifies a component that does not belong to the categorization of a Knowledge Based System.
