Which statement correctly describes a computer-controlled machine used in manufacturing?

• A. It operates manually, without programs
• B. It uses computer programs to control manufacturing operations
• C. It is a purely mechanical device
• D. It requires no maintenance

Answer: (B)

Computer-controlled manufacturing equipment relies on software instructions to guide its actions. The essence is that these machines execute operations based on computer programs loaded into their control systems, allowing automated, precise, and repeatable production steps. That’s why using computer programs to control manufacturing operations is the best description. It captures how the machine receives coded instructions and performs tasks automatically, rather than relying on manual input or purely mechanical motion. Operating manually without programs isn’t describing a computer-controlled system, since there’s no software directing the work. A purely mechanical device likewise lacks the electronic control and programming that define computer-controlled machines. And while maintenance is needed for equipment, the idea that it requires no maintenance isn’t correct.
