ITPEC IP April 2022 Question 94
Which of the following is the most appropriate term for information in large quantities and in diverse forms that has real-timeness and is expected to help obtain knowledge useful for decision-making?
Explanation
Big data — information in large quantities and diverse forms, generated in real time, from which knowledge useful for decisions is expected.
Big data is usually characterized by three Vs: volume (a huge quantity), variety (text, images, sensor readings, logs, social media posts) and velocity (generated and processed in real time). Analyzing it with statistics, data mining and AI reveals patterns, such as customer behavior, demand trends or signs of equipment failure, that support decision-making.
Answer (a)
Why not others:
- •(b) Diversity — accepting and using people of different sex, age, nationality and background in an organization; a human-resource concept
- •(c) Core competence — a company's core capability that competitors cannot easily imitate
- •(d) Crowdfunding — raising money from many people over the Internet
Key rule: Volume, variety and velocity define big data; its value lies in analyzing it to support decisions.
