Which set contains only examples of computer hardware?

### Why this is right Each item in the correct set is a physical device or component. The other sets mix physical devices with programs, which are software. ### The concept Hardware includes input devices, output devices, memory, and storage components. Software is the set of programs and instructions that runs on hardware. A computer system needs both: hardware performs physical operations, while software directs those operations. ### The other options - **B. Spreadsheet, operating system, keyboard, browser**: The keyboard is hardware, but the other items are software. - **C. Web page, processor, word processor, monitor**: The processor and monitor are hardware; a web page and word processor are software. - **D. Operating system, browser, spreadsheet, word processor**: These are all software examples. ### Terms - **Operating system**: Software that manages a computer's resources and provides services for applications. ### Remember A physical component is hardware; a program or instruction set is software.
