Big Data

Which of the following typically create large sets of data?

• Social Media Sites

• Hospitals

• A and B only

• A, B, and C

Why are computers used to process digital data?

• Computer are much faster and more efficient than humans when searching large data sets

• Computer can more quickly scan and sort through giant sets of data

• It is way more fun as humans

  do not like searching large data sets by hand

• A and B only

• A, B, and C

Which of the following operations can computers perform on large data sets to help make sense of the data?

• computers can remove useless stuff from the data way faster than humans

• computers can add things to

  the data to make the data easier to read / examine

• computer software could be

  used to compress the data

• A and B only

• A, B, and C

Which of the following is possible when computers and programs are used to manipulate large data sets?

• groups or patterns may emerge that need to be examined
• useless stuff can be removed to make the data easier to examine
• ways to use the data can be discovered once junk is removed from the data
• A and B only
• A, B, and C

Scanning large data sets can help companies and individuals locate which of the following in the large data sets?

• repeating groups or patterns in the data
• how the data relates to the business and how the business operates

• large data sets may provide information that helps solve problems
• A and B only
• A, B, and C

Which of the following can help make sense of large sets of data?

• Algorithms that quickly sort through the data looking for groups or patterns
• USB drives
• A and B only
• A, B, and C

Which of the following would be a valid reason to analyze a large set of data?
