Homework Help: Questions and Answers: Data collected from your smartphone online gaming sessions internet searches and smart appliances best illustrate which feature of big data?
A. Veracity
B. Velocity
C. Variety
D. Volume
Answer:
First, let’s understand the key concepts of big data features:
Big data is typically defined by the 4 V’s: Volume, Variety, Velocity, and Veracity. Each of these represents a different feature of big data.
Given Options: Step by Step Answering
a) Veracity
- Veracity refers to the quality and trustworthiness of the data. It’s about ensuring that the data is accurate, clean, and reliable.
- Since the question is asking about different sources (smartphone, online gaming, etc.), veracity is not the most fitting choice because it focuses on data accuracy rather than its origin or nature.
b) Velocity
- Velocity is the speed at which data is generated and processed. For example, data generated in real-time or near real-time (e.g., streaming data, social media updates) relates to velocity.
- While some of the data sources in the question (like online gaming or internet searches) can generate data quickly, this doesn’t capture the whole picture of data being collected from multiple diverse sources.
c) Variety
- Variety refers to the diverse sources and types of data. This feature highlights the wide array of formats and origins, such as structured data (databases), unstructured data (text, images, videos), and semi-structured data (JSON, XML).
- The examples given in the question—smartphones, online gaming sessions, internet searches, and smart appliances—represent diverse sources of data. This fits with the concept of variety in big data.
d) Volume
- Volume refers to the size or amount of data generated. Big data involves large datasets that require special tools and technologies for storage and analysis.
- While these data sources might generate large amounts of data, the question emphasizes the different sources more than the size of the data.
Final Answer:
Based on the above analysis, the correct answer is:
C. Variety
This is correct because the data comes from various sources such as smartphones, online gaming, internet searches, and smart appliances, highlighting the diversity of data types and formats.
