Terminology and storage granularity: Do most computers “store binary data in groups of 32 bits called double words (DWORDs),” or is 32-bit grouping platform-dependent while the fundamental storage unit remains the 8-bit byte?

Difficulty: Easy

Correct Answer: Incorrect

Explanation:


Introduction / Context:
Computers organize data in multiple granularities: bits, bytes, words, and wider registers. This question clarifies a common misconception by examining whether 32-bit “double words” are universally the primary storage grouping, or whether such terminology is architecture-specific while the byte remains fundamental.


Given Data / Assumptions:

  • A byte universally equals 8 bits in modern systems.
  • Word size varies by architecture (16-bit, 32-bit, 64-bit, etc.).
  • “DWORD” is a conventional term in some ecosystems (for example, Windows/x86) meaning 32 bits.


Concept / Approach:
The fundamental addressable unit in memory is the byte (8 bits). While some platforms historically used 32-bit words and popularized the term “double word,” modern systems are often 64-bit, and other embedded systems may be 8-, 16-, or 32-bit. Therefore, claiming that most computers store data in 32-bit groups called DWORDs is overly general and inaccurate across the industry. The correct general statement is that computers store data as bytes, words, and larger units depending on architecture and data type.


Step-by-Step Solution:

Recognize the universal 8-bit byte as the base addressable unit.Note that “word” size depends on architecture; 32-bit was common, 64-bit is now typical on desktops/servers.Understand that “DWORD” (32-bit) is platform-specific jargon, not a universal rule.Conclude the blanket statement is inaccurate; storage granularity is not always 32 bits.


Verification / Alternative check:
Inspect ABI documentation for different CPUs: x86-64 defines 64-bit general-purpose registers and native word sizes; many MCUs define 8-, 16-, or 32-bit words.


Why Other Options Are Wrong:
Saying “Correct” generalizes improperly; restricting to legacy 16-bit CPUs or claiming it is true only for memory or networking ignores broader architecture diversity.


Common Pitfalls:
Confusing a compiler’s data type sizes with hardware word size; assuming Windows terminology applies to all systems.


Final Answer:
Incorrect
