A large number of text messages are received by Twitter each year making Twitter one example of Big Data. What data characteristic represents this large number of text messages?

AVeracity

BVelocity

CValue

DVariety

Show Suggested Answer

Suggested Answer: B

Velocity is one of the four V's of Big Data, along with Volume, Variety, and Veracity. Velocity refers to the speed at which data is generated, collected, and processed. A large number of text messages received by Twitter each year is an example of high-velocity data, as it requires real-time or near-real-time processing and analysis to extract insights and value from it. High-velocity data poses challenges and opportunities for business data analytics, as it requires efficient and scalable data infrastructure, streaming analytics, and timely decision-making.

I'd go with B) Velocity. The speed at which all that data is generated and processed is the defining feature.

I thought veracity was about the accuracy of data, but I’m not confident. Maybe it’s not the right choice here?

I practiced a similar question where velocity was the answer, so I’m leaning towards that for this one too.

I'm not entirely sure, but I feel like variety might be relevant since Twitter has different types of messages, like text, images, and videos.

I remember discussing the characteristics of Big Data, and I think velocity refers to the speed of data generation, which fits with the large number of messages.

Hmm, I'm a bit torn between Velocity and Variety. The large number of text messages could be seen as a form of Variety, but Velocity also seems like a reasonable answer. I'll have to weigh the options carefully before selecting my final answer.

I think the answer is Velocity. The question is specifically asking about the data characteristic that represents the large number of text messages, and Velocity is the best fit for that. I'm pretty confident in this one.

Okay, let me break this down. Veracity is about the truthfulness and accuracy of the data, which doesn't seem to be the focus here. Value is about the usefulness of the data, which also doesn't seem to be the main point. I'm leaning towards Velocity, but I'll double-check the definitions to be sure.

Hmm, I'm not sure about this one. The large number of text messages could also be considered a form of Variety, since it's a diverse set of data. I'll have to think this through a bit more.
