Concept explainers
Big Data:
Big Data is large amount of structured, semi-structured or unstructured data generated by mobile, and web applications such as search tools, web 2.0 social networks, and scientific data collection tools which can be mined for information.
Three characteristics of big data:
The big data is categorized into 3Vs as follows:
- Volume of data
- Variety of data
- Velocity
Volume – It refers to the amount of data being stored. With the advent of Internet and Social media, organizations are using multiple technologies to interact with the end users and these technologies are generating mountains of data.
Velocity – Velocity refers to the speed of data processed. With the advent of Internet and social media, the business response times have shrunk and the increase in the number of different data streams has resulted in the velocity of data growth.
Variety – Variety refers to the number of types of data. The data comes in multiple data formats, where a great portion of it cannot be handled by operational databases.

In the second blank, enter the array contents after one more partition of the left-hand subarray resulting from the first partition. In the third blank, enter the array contents after one more partition of the right-hand subarray resulting from the first partition. Print the numbers with a single space between them. Use the algorithm we covered in class, in which the first element of the subarray is the partition value. Question 1 options: Blank # 1 Blank # 2 Blank # 3arrow_forward1.
