The MAU-169 series computer control group consists of which components?

• A. Control section
• B. Power unit
• C. Data logger
• D. Interface module

Answer: (A)

The question tests your ability to distinguish the part of the MAU-169 that performs the actual processing and control tasks from its supporting components. The computer control group is defined by the portion that handles the processing and control logic, so the correct component is the control section. The other items—the power unit supplies power to the assembly, the data logger records data, and the interface module handles communication with external devices—do not perform the control processing and are considered separate support functions. In short, the brain-like function is the control section, which is why it’s the best choice.
