Which of the following are not the 4 Vs of Big Data?
Answer: D
The one that is not among the 4 Vs is Verification.
Big data is usually described by four Vs: Volume (the sheer quantity of data), Velocity (the speed at which it is generated and processed), Variety (the many forms it takes) and Veracity (its reliability and accuracy).
Verification sounds like veracity but is not one of the four Vs; velocity, volume and variety are.
Some writers add further Vs such as Value and Variability, but verification is not among the defining characteristics of big data.
