Commercial data processing (CDP) relies on robust mainframe computer systems, which consist of various hardware components. Key elements include a CPU with memory, input devices, multiple output devices, a backing store, terminals, and an operator's console. Mainframes enhance efficiency, allowing for faster order processing and reducing error rates due to built-in checks. CDP simplifies customer management by storing up-to-date customer lists on the backing store, ensuring that businesses can effectively track and serve their clientele.
