Final answer:
Rule-based knowledge is installed in the Knowledge Source component of the blackboard architecture, which contributes specific expertise to problem-solving, while the blackboard serves as a shared workspace.
Step-by-step explanation:
The rule-based knowledge is installed in the Knowledge Source component of the blackboard architecture. In the context of blackboard systems, rule-based knowledge components, also known as knowledge sources, are akin to experts that contribute their specific expertise to solve parts of a problem. The blackboard itself serves as a shared workspace where the problem state is displayed, and the Control component determines which knowledge source to use at any given time based on the current state of the blackboard.
