Answer to Question 1

FALSE

Answer to Question 2

BigData is a term used to describe data collections that are characterized by huge
volume, rapid velocity, and great variety. Considering volume, BigData refers to data sets that
are at least a petabyte in size, and usually larger. Additionally, BigData has high velocity,
meaning that it is generated rapidly. BigData is varied. BigData may have structured data, but it
also may have free-form text, dozens of different formats of Web server and database log files,
streams of data about user responses to page content, and possibly graphics, audio, and video
files. BigData analysis can involve both reporting and data mining techniques. The chief
difference is, however, that BigData has volume, velocity, and variation characteristics that far
exceed those of traditional reporting and data mining.
