Which component provides the operator with an X-Windows terminal displayed at the MCW?

• A. Monitor and Control Display (MCD) software component
• B. Control and Monitor Display (CMD) computer software configuration item (CSGI)
• C. Terminal Display Interface (TDI)
• D. Display Coordinator (DC)

Answer: (B)

Providing the operator with the graphical X-Windows terminal at the Monitor and Control Workstation is handled by the Control and Monitor Display computer software configuration item. This CMD CSGI is the software package that defines and delivers the operator-facing interface, including the X-Windows session, window layouts, and interactive screens used for monitoring and control. It’s the component responsible for presenting the graphical environment to the operator, while other components contribute to display functionality or coordination but do not supply the operator terminal itself. The Terminal Display Interface is a lower-level interface used by display components, and the Display Coordinator handles coordinating multiple displays, not the individual operator terminal experience.
