In a distributed processing system, which device makes the intelligent decisions?

• A. Server
• B. Control panel
• C. Biometric sensor
• D. Keypad

Answer: (B)

In distributed processing, the decision-making happens at the local controller, which in building automation is the control panel. This device runs the control logic, processes inputs from sensors, and decides which outputs to activate, such as turning on fans, dampers, or alarms. The server’s role is typically to store data, host programming, and coordinate systems at a higher level, but it doesn’t usually make immediate control decisions. Sensors like biometric devices or user input devices like keypads provide data or commands, yet they don’t determine how the system should respond on their own. So the control panel is the intelligent, autonomous decision-maker that translates sensed conditions into actions.
