Processing refers to which part of the computer?

• A. Data entry
• B. The parts of the computer that run programs
• C. The display of outputs
• D. The network interface

Answer: (B)

Processing happens in the part of the computer that executes instructions and transforms data—the processor. This is where the program’s steps are carried out: the CPU fetches instructions from memory, decodes them, and executes operations like arithmetic, comparisons, and controlling the flow of the program. In short, the processor is the engine that runs programs and turns input into output and useful actions.

Data entry devices are for bringing information into the system, not for performing computations. The display of outputs shows results after processing has occurred, and the network interface handles communication with other machines.
