Which one of the following statements about hardware is true?

Question

BlackTom AI · Accepted Answer

Hardware denotes the physical, tangible parts of a computing system — processors, memory chips, storage drives, motherboards, sensors, displays, network interfaces and so on. A digital system is an arrangement that processes, stores or transmits information using discrete (digital) signals. These two concepts are fundamentally linked: hardware provides the physical platform on which instructions execute and data are stored or moved.

Relevant knowledge points and concepts
- Hardware = physical components of a computer or device.
- Software = programs and data that instruct hardware what to do.
- Digital systems require physical substrates to operate (even cloud services run on physical servers, switches, disks and power systems).

Step-by-step reasoning
1. Identify what a digital system does: processing, storage, communication of digital information.
2. Determine what enables those functions: physical components (CPUs, memory, storage, network gear) perform electrical operations; these are hardware.
3. Recognize that software alone cannot execute without hardware; even virtualized environments or containers ultimately depend on machine hardware.
4. Conclude that hardware is therefore a vital component of all digital systems.

Why the correct answer is correct
Answer a states that “Hardware is a vital component of all digital systems.” Given that every executable program, virtual machine, or cloud service ultimately runs on physical electronics, hardware is indispensable — making (a) true.

Why the other options are incorrect
- b is false because it implies some digital systems lack hardware; in reality software or virtual systems still rely on hardware beneath them.
- c is misleading/false: systems that “do not use software” are not “referred to hardware”; hardware is the physical parts, not a name for software-less systems.
- d is false because modern digital systems do rely on hardware; they cannot operate without it.

Conclusion
Therefore the correct choice is (a), which matches the provided answer.
