Answer to Question 1

TRUE

Answer to Question 2

Because Big Data is huge, fast, and varied, it cannot be processed using traditional techniques. MapReduce is a technique for harnessing the power of thousands of computers working in parallel. The basic idea is that the Big Data collection is broken into pieces, and hundreds or thousands of independent processors search these pieces for something of interest. That process is referred to as the Map phase. For example, a dataset having the logs of Google searches is broken into pieces, and each independent processor is instructed to search for and count search keywords. As the processors finish, their results are combined in what is referred to as the Reduce phase. The result is a list of all the terms searched for on a given day and the count of each.
