Big data collection is different than normal data collection. Here, we are to see whether you understand much about big data or not. Try your best, answer these simple questions and get an as good score as you can. Are you ready? Let's head towards it then.

Questions and Answers

1.

Big data challenges include all the following except
- A.
  
  Virtually
- B.
  
  Capturing data
- C.
  
  Visualization
- D.
  
  File storage
Correct Answer
A. Virtually

Explanation
The given question asks to identify the option that is not a challenge of big data. The options provided are "Virtually," "Capturing data," "Visualization," and "File storage." Among these options, "Virtually" does not represent a challenge in the context of big data. It is unclear what "Virtually" refers to in this context, but it does not align with the challenges typically associated with big data such as capturing, visualizing, and storing large volumes of data. Therefore, "Virtually" is the correct answer as it does not fit the category of big data challenges.

Who coined the word big data?
- A.
  
  John Brady
- B.
  
  Timothy Philip
- C.
  
  Samuel John
- D.
  
  John Mashey
Correct Answer
D. John Mashey

Explanation
John Mashey is credited with coining the term "big data." He first used the term in the early 1990s to describe the challenges of dealing with large and complex datasets. Mashey's work focused on the need for new tools and techniques to analyze and extract value from these massive amounts of data. His contributions to the field of data science and his use of the term "big data" have had a significant impact on the way we understand and approach data analysis today.

Big data requires a set of techniques and technologies with new forms of integration to reveal insights from data sets that are diverse, complex, and of a massive scale.
- A.
  
  Fairly true
- B.
  
  Not true
- C.
  
  Often true
- D.
  
  Seldom true
Correct Answer
C. Often true

Explanation
The statement suggests that big data often requires new techniques and technologies to analyze and extract insights from large and complex data sets. This implies that big data is typically diverse, complex, and of a massive scale, which aligns with the definition of big data. Therefore, the answer "Often true" is an appropriate response to the statement.

The following are the 3Vs in big data except
- A.
  
  Velocity
- B.
  
  Volume
- C.
  
  Virtually
- D.
  
  Variety
Correct Answer
C. Virtually

Explanation
The three Vs in big data refer to Velocity, Volume, and Variety. These three factors represent the key characteristics of big data. Velocity refers to the speed at which data is generated and processed, Volume refers to the sheer amount of data being collected, and Variety refers to the diversity of data types and sources. "Virtually" does not fit into this context as it does not represent a characteristic of big data.

The following are concepts of big data, except
- A.
  
  Digital learning
- B.
  
  Machine blueprint
- C.
  
  Virtually
- D.
  
  Variety
Correct Answer
C. Virtually

Explanation
Virtually is not a concept of big data. Big data refers to the large volume, velocity, and variety of data that cannot be easily managed or analyzed using traditional methods. Digital learning, machine blueprint, and variety are all concepts related to big data. Digital learning refers to the use of technology and digital resources for educational purposes, machine blueprint refers to the design and architecture of a machine or system, and variety refers to the different types and formats of data that are part of big data.

- D.
  
  1970s
Correct Answer
A. 1990s

Explanation
The term "big data" was coined in the 1990s. During this time, there was a significant increase in the amount of data being generated and collected due to advancements in technology and the internet. The term was used to describe the challenges and opportunities that arose from the massive amounts of data that organizations were starting to collect. This led to the development of new tools and technologies to store, analyze, and extract insights from this large volume of data.

Factory work and cyber-physical systems may have
- A.
  
  6C system
- B.
  
  3V system
- C.
  
  4C system
- D.
  
  4A system
Correct Answer
A. 6C system

Explanation
The given options are different systems that could be related to factory work and cyber-physical systems. Out of the options provided, the 6C system is the most suitable because it aligns with the context of the question. The 6C system is a concept that refers to the six key components of cyber-physical systems, which are computation, communication, control, coordination, cognition, and configuration. These components are essential in the integration of physical and computational elements in a factory setting or any system that involves cyber-physical interactions.

The use and adoption of big data within governmental processes allows efficiencies in terms of this, except
- A.
  
  Cost
- B.
  
  Value
- C.
  
  Productivity
- D.
  
  Innovation
Correct Answer
B. Value

Explanation
The use and adoption of big data within governmental processes allows efficiencies in terms of cost, productivity, and innovation. However, the one aspect where it may not provide efficiencies is in terms of value. While big data can provide valuable insights and information, the value derived from it may not always outweigh the costs associated with its collection, storage, and analysis. Therefore, value is the exception in this context.
