Final answer:
The term 'Viscosity' is not one of the 4 Vs of Big Data. The 4 Vs consist of Volume, Velocity, and Variety.
Step-by-step explanation:
Within the context of Big Data, the 4 Vs represent key attributes that make handling and processing such data challenging and distinct from traditional datasets. These attributes are Volume, referring to the immense size of the data; Velocity, indicating the speed at which new data is generated and moves; and Variety, which captures the various forms and sources of data. The correct option that is NOT one of the 4 Vs of Big Data in this list is Viscosity. 'Viscosity' is a term related to the physics of liquids and has no standard definition or relevance in the context of Big Data's core characteristics.
