解説
問 25
Incorrectア
“3C” is not a term that represents the three elements of Big Data. It may bring to mind something like the 3C analysis used for environmental analysis in marketing (Customer, Competitor, Company), but it has nothing to do with the volume, velocity, and variety asked about in the question.
Incorrectイ
“3D” is not an established term referring to the characteristics of Big Data. It suggests three dimensions (3-Dimension), but it does not match the initial letter V of Volume, Velocity, and Variety, so it is wrong.
Incorrectウ
“3G” refers to the third-generation mobile communication system for mobile phones, and has nothing to do with the three elements of Big Data. It does not correspond to the initial letter of any of Volume, Velocity, or Variety, so it is wrong.
- エ
正解 The correct answer is choice エ, 3V. Big Data is characterized by three elements: large volume (Volume = amount); frequent updates, that is, rapid generation and processing (Velocity = speed); and wide variety (Variety = diversity). Because all three words start with the letter “V”, they are collectively called “3V”. The question’s “large volume, frequent updates, and wide variety” correspond to Volume, Velocity, and Variety respectively, so エ is correct.
ここがポイント
- The 3V of Big Data is the collective name that groups the three elements — Volume (amount = large volume), Velocity (speed = frequent updates), and Variety (diversity = wide variety) — under their common initial letter V.
- Keeping in mind that “large volume”, “frequent updates”, and “wide variety” correspond to Volume, Velocity, and Variety respectively makes it easier to choose the correct answer.
