Which key is used to execute programs from a centrally located computer storage device?

• A. Manual Data Input
• B. MDI Mode
• C. DNC
• D. MEM Mode

Answer: (C)

The correct answer is C, DNC (Direct Numerical Control), which is used to execute programs from a centrally located computer storage device. DNC systems allow CNC machines to directly receive and run programs that are stored on a central server or computer. This process streamlines operations by allowing multiple machines to draw from a common repository of programs, ensuring that the latest versions are readily available and minimizing the risk of errors associated with manual program input. DNC enhances efficiency by facilitating centralized control over the programming and monitoring of CNC machines, which is particularly beneficial in environments where various CNC machines need access to the same operational data. The other choices refer to different modes or input methods. Manual Data Input involves entering data directly into the machine's interface, which is not what the question specifies. MDI (Manual Data Input) mode is primarily used for immediate manual input of instructions without relying on external storage. MEM (Memory) mode pertains to running programs that are stored in the machine's internal memory, rather than from an external storage device. Each of these methods serves different purposes in CNC operation, but they do not provide the same centralized execution capability as DNC.
