Question

Select the missing words: <…> is any physical part of the <…> system that you can physically touch, pick up and move.

BlackTom AI · Accepted Answer

Hardware is any physical part of a digital system that you can physically touch, pick up and move.

1. Relevant knowledge points and concepts
- Hardware vs software: Hardware refers to tangible, physical components (e.g., keyboard, monitor, hard drive). Software refers to intangible programs and data (e.g., operating systems, applications).
- Digital vs manual system: A digital system processes information electronically; a manual system relies on human physical processes or paper-based methods.

2. Step-by-step reasoning
- The sentence describes something you can "physically touch, pick up and move." That requirement identifies a tangible object.
- Tangible parts of a computing environment are called hardware.
- The phrase uses "<…> system." In the context of computing, the common collocation is "digital system" (i.e., computer/digital system), not "manual system." Therefore the second blank should be "digital."

3. Calculations / intermediate steps
- No numerical calculations are required. Logical identification steps:
  a) "physically touch" => tangible => hardware.
  b) context of computing systems => digital system rather than manual.

4. Why the correct answer is correct
- "Hardware, digital" fits: hardware denotes the physical components, and "digital system" correctly names the type of system those components belong to. The phrase reads correctly as "Hardware is any physical part of the digital system that you can physically touch, pick up and move."

5. Why the other options are incorrect
- a. Software, digital: Software is intangible and cannot be physically touched or picked up, so it contradicts the "physically touch" clause.
- b. Software, manual: Same problem as (a) — software is not physical. Also "manual system" is less appropriate for computing context.
- d. Hardware, manual: While hardware is correct for the first blank, pairing it with "manual" is misleading because the standard phrase refers to a "digital system" (hardware belongs to digital/computer systems); "manual" implies non-digital, paper-based processes.

6. Conclusion
- The correct choice is "Hardware, digital," which matches the provided answer.
